Then & Now: Antarctic Ventures

UND Discovery Magazine - Mon, 2013-12-09 09:15

Then - Lessons for the Future Frozen in Time and Ice Basic research done yesterday and today pays dividends in knowledge and applications

John Reid wasn’t about to let it go.

A critical editorial in the Harvey (N.D.) Herald got Reid’s dander up, and he ventured a friendly retort.

The Herald had taken Reid to task on March 25, 1965, for apparently wasting taxpayer money after the University of North Dakota geologist had $10,000 worth of Antarctic glacial ice sent to his 5-degree-cold laboratory in Leonard Hall.

Surely, there must have been sufficient ice for research in Grand Forks after the long winter, the paper suggested.   How about refrigerator ice?  Why go 10,000 miles to the bottom of the world to bring home North Dakota’s primary winter export?

The irony was probably too great for the Herald’s writer to pass up.

But this editorial was about more than slabs of ice from afar. That was just the attention-getter.  It echoed a common indictment in scientific circles back then and that persists today: “What practical value is basic scientific research?”

Reid, at the time a UND associate professor of geology who actually paid for the ice shipment out of pocket, could have lectured the editorial writer all day on the geological value of glacial ice versus what’s found in your everyday icebox, but he didn’t.  His reply zeroed on the larger point.

“Scientists are always pressured to justify their research,” he wrote. “Regardless of how often we explain that by far the greatest number of practical inventions [has] resulted from some form of basic research on the part of a scientist at a university, people will not readily accept this.” Reid pointed to the advent of the laser as a discovery that had no immediate practical application, and that Madam Curie’s notion to isolate radium was a study of the unknown rather than a conscious step toward atomic power or detection of pollution or cures for cancer.

“If the researcher in the university is forced to find practical reasons for his research, science will be stifled,” Reid wrote. “It is only by searching beyond this boundary that technology will be advanced.”

Fast-forward nearly 50 years: Reid, now 80 and long retired from UND, says the views he shared in his letter to the editor have not waned a bit.

“Basic research may seem to be a waste of effort and time by many,” Reid said from his home in Fort Collins, Colo. “But even negative results are critical to understanding. Science progresses by trial and error.  The desire for practical application of research is understandable, but no one can foresee the future, and the majority of practical discoveries has come from basic research and serendipity!”

Words of wisdom from a longtime researcher who’s seen it all and done it all — mostly while at UND.

But even more than a researcher, Reid is probably most proud of his legacy as a teacher. There’s an underlying sense, reading through Reid’s three-page response to the Harvey Herald, that rather than attacking the writer, he is teaching the writer — and by extension the public — about the value of basic scientific research.  He was always teaching.

Reid, a giant in the field of geology with two major terrain features in Antarctica — a glacier and a mountain ridge — named after him, was a colossus in the classroom, too.  For nearly 40 years, he was regarded as one of UND’s outstanding teachers and scholars. He was named North Dakota Professor of the Year in 1996, and received several other awards for teaching excellence during his career.

“My greatest achievement as a faculty member, without a doubt, was mentoring my students,” Reid said. “I continue to hear from many, and am very proud of their achievements.”

Teaching is in Reid’s blood. The Melrose, Mass., native’s childhood was strongly influenced by his mother, a former one-room school teacher.  As he grew up, Reid’s life lessons were enhanced when his parents took in “roomers” for supplementary income. The roomers included professional men, unwed mothers, temporarily abandoned children, and war-separated families. These experiences would serve him well years later as a tough but fair teacher and mentor.

“I developed a strong sensitivity to people’s problems.  As a result, students quickly learn that I care about them,” he once wrote in a paper about his contributions as an undergraduate teacher.

Outside the classroom, Reid says his fondest memories were times spent with students on field research expeditions, especially those in the Martin River Glacier Area of south-central Alaska.

Reid’s name may be stamped on Antarctica, but much of his geological reputation was earned at the other end of the planet in places such as Alaska, Arctic Canada, and Greenland.

A much-hailed research discovery took place on a lake in the Martin River Glacier Area in the summer of 1963, when Reid and students began investigating a massive, 200-ton (100-feet-wide and three-football-fields-long) dirt-covered iceberg that suddenly “popped up.”  The discovery suggested new mechanisms for the origin of icebergs and provided supporting evidence to existing theories on ice flow.  Their research was published in the Journal of Glaciology.

Reid said the work was more valuable for his students than anything that could be demonstrated in a traditional classroom.

“They learned much and so did I,” he said.

Reid actually only spent a few months in Antarctica in the winter of 1958-59. The conditions were brutal as his team camped 45 miles from the nearest shred of civilization.

“That was in the days when comfort and communication were more primitive,” he recalled. “Our tents, for example, had no floors, just the snow.”

Still, it was a fruitful experience. It was here that he chiseled rare chunks of surface glacier ice from the Ross Ice Shelf, the largest mass of floating ice in the world (500 miles long by 500 miles wide, moving a half-mile per year — the “speed of light” for geologic time).  It was this glacial ice that Reid would eventually have shipped to UND a few years later, making a splash in local and national media — and one aforementioned editorial.

Reid and UND enjoyed the publicity that the exotic Antarctic ice brought. More practically, Reid used the samples to educate his students and to study geological theories of the time.

“The formation of mountains is perhaps the most embarrassing problem that geologist have,” Reid wrote in 1965. “The pertinence of this analogy lies in the fact that ice is a rock, composed of the mineral, ice. Ice deforms plastically under very slight pressures. Hence, we can watch a mountain form in ice form in a very short period of time. To see the same amount of deformation in other types of rocks would require hundreds of thousands of years.”

Reid retired from UND in 1999, but UND’s geomorphological research in high, cold places of the world didn’t end with his departure. Reid said he’s quite aware of the work that another UND faculty member and fellow geomorphologist, Jaakko Putkonen, is doing with his own students in Antarctica and the Himalayas.

“I applaud Jaakko for his dedication to glacial geomorphology and to his willingness to involve students in his research,” Reid said. “Students learn best from direct participation.”

In 2000, Reid and his wife of 57 years, Barbara, moved from Grand Forks to Fort Collins, close to the Rocky Mountain National Park, where they enjoy hiking.

Ever the teacher, Reid continued working with his last Ph.D. student after retirement.  He also volunteered for five years at local high schools in geoscience classes, organizing rock and mineral collections. Today, he assists three days a week in the computer labs of a nearby elementary school, and volunteers as an ombudsman at two nursing homes for the County Office on Aging.

“So, even though I have turned 80 — I keep happily busy.” And, apparently, still happily teaching.

Now - Antarctica Yields Climate Clues for Earth, Beyond

In an era soaked in a digital deluge where online is the place to be, Jaakko Putkonen and his student teams blaze — or let’s say freeze — a totally different path.

This University of North Dakota geomorphologist, a native of Finland, spends most of his field time in Antarctica and other frigid remote places.

Most recently, Putkonen took himself and a team of UND graduate and undergraduate students to a remote interior desert — an ice-free valley — along the largest mountain range in Antarctica. They were chasing clues to how and why landscapes change. They also retrieved vital “data loggers” placed in that Antarctic desert by Putkonen and another student team a year earlier.

“We wanted to collect data and more samples and to go to places this time that we couldn’t get the last time we were there (in December 2010 to January 2011),” said Putkonen. He’s conducted research in several of the remotest, highest and coldest locations in the world, including Antarctica, Greenland, Spitsbergen, Lapland, and in the Himalaya Mountains.

“It’s a physically punishing trip because you’re working 2,500 meters above sea level in a truly rough landscape. And when I say rough, I mean boulders on top of boulders. After most days, we were mentally exhausted just because we had to plan every step, jumping from boulder to boulder, as falling down is not really an option in a location where the nearest medical help is 1,000 miles and several days away.”

The data loggers and sensors were placed at various locations in the desert to gather a year’s worth of information.

“All that equipment had to go through an Antarctic winter, which can be truly brutal,” Putkonen said. “We set all the sensors and data loggers up on plumbing-grade zinc pipe anchored with boulders.”

Jaakko Putkonen: The data generated by rock samples will provide an understanding not only of the evolution of the Antarctic landscape but also of similar environments beyond Earth, such as that of Mars.

Rocks of ages

Putkonen and one of his Ph.D. students, Theodore Bibby, are extracting scientifically usable information from the piles of data and samples they gathered. Part of that work is being done in a unique lab at the Harold Hamm School of Geology & Geological Engineering, part of the College of Engineering & Mines.

It’s basically about dating rocks.

“We’re trying to understand how the Antarctic landscape evolved over both short and long time periods,” Putkonen said. “We ask some straightforward questions, such as how is the dirt moving around there like it does here (in North Dakota) in a big rainstorm or with North Dakota’s famous winds. The dirt that’s being eroded somewhere is being deposited somewhere else — the landscape changes.”

Extracting usable data from all the samples requires using an analytical method that measures the rare radioactive isotopes in each specially prepared rock sample.

“We know that rocks that are buried, for example, deep below the ice sheet don’t get bombarded by high-energy particles, and we can detect that,” Putkonen said.

Rocks that are exposed on the Earth’s surface, on the other hand, accumulate rare isotopes as a result of particle bombardments from outer space. The isotopes’ effects can be studied in Putkonen’s lab.

“We can measure the amount of the isotope and back-calculate how long that particular rock has been sitting there out in the open,” Putkonen said. “Some rocks from deep below the surface that are millions of years old have never been to the surface, but when a glacier plucks them up and then the ice melts, those rocks are exposed at the Earth’s surface.”

The cosmogenic isotope analysis is a lot like the radio carbon-14 dating system that is routinely used to determine ages for old wood products such as furniture, paintings, old buildings and other man-made structures.

“But the isotope analysis allows us to go much further back in time — millions of years — than can carbon-14 dating, which only goes back about 50,000 years,” Putkonen said.

This National Science Foundation-backed research aims to describe changes in the Antarctic landscape over time, but it has also detected natural changes in climate. This could help scientists understand more about human-generated climate change, which also is impacting landscapes around the world in ways that aren’t clearly known.

Putkonen’s research also extends to planetary studies.

“When we look at Mars, for example, there are areas that look very similar to where we were recently in Antarctica,” Putkonen said. “And it turns out that it is much cheaper to go to Antarctica than Mars. We are building insights about the Martian environment by doing field research in Antarctica.

“It is funny how basic research often works. The payoffs may not be obvious when you start, but eventually they come to light in a surprising and unexpected way.”

Inspiring leaders

Last summer, Putkonen took UND students on a three-week trip to Nepal for a course on the basics of field geology high in the Himalayas.

“To learn geology you have to go where the geology is, which is in the field,” said Putkonen, who started doing science trips to Nepal during his postdoctoral work.

But Putkonen doesn’t discount the work he does in the traditional classroom.

“My task is not just to deliver facts for the students in preparation for a skillful workforce,” he said. “My task is to unleash the imagination, and motivate the students to innovate and to become leaders instead of followers.”

Then & Now: Robinson’s Legendary State History

UND Discovery Magazine - Mon, 2013-12-09 09:10
Then - Standing the Test of Time Elwyn Robinson's Masterwork Remains Relevant After Half a Century

Not many textbooks are used for 50 years. But Elwyn B. Robinson’s History of North Dakota has stood the test of time.

It’s the best state history ever written and it’s still relevant, said Gordon Iseminger, Chester Fritz Distinguished Professor of History.

Iseminger, a long-time colleague of Robinson, has been at UND for 52 years.  He is the longest-serving faculty member on campus and the longest-serving state employee. He is also one of very few faculty to have had children and grandchildren of former students in his classes.

“Robinson absorbed North Dakota history,” Iseminger said.  “I don’t see how we can not use the book. The themes are still mostly relevant.  Circumstances have changed, but not so much the themes.”

Libby and Robinson
Iseminger, who is known for his high standards, is a historian’s historian. His research includes local history, Germans from Russia, and a series of essays on former UND history chair Orin Libby, one of UND’s “grand old men” and the man who brought Robinson to UND.


“Libby retired in 1945, and his presence was still palpable in 1962,” said Iseminger. “He doted on maps, didn’t suffer fools gladly, and was influential in starting the State Historical Society, the State Library, the State Museum, and the State Park System.”

When Iseminger joined the faculty in 1962, he said, research and scholarly work were not emphasized as much as they are today, and Robinson was able to spend more time on his masterwork. “His work was painstaking, almost plodding,” Iseminger said. “He spent 20 years on it, and it shows.”

There are other state histories, Iseminger said, but they are not as comprehensive. Following Robinson is tough, he said, adding he would not want to write a more current history.  Kim Porter, professor of history, stepped up to the challenge and produced a new volume, North Dakota:  1960 to the Millennium.

“I give Dr. Porter a lot of credit,” he said. “She has an agricultural history background, and she did well at summing up the 30 or 40 years of North Dakota’s history since Robinson’s book was published. It was a daunting task, but Dr. Porter, although from Iowa, has adapted to the state and to being a North Dakotan.”

Still relevant

Robinson identified six themes of North Dakota history that are mostly still relevant: remoteness, dependence, radicalism, economic disadvantage, the “too-much mistake,” and adjustment. Remoteness meant that the state was influenced by its distance from national centers. Dependence on external pricing for furs, grain, and other commodities defined profit and loss. Radicalism became the state’s answer to these themes, resulting in the birth of the Nonpartisan League and the establishment of the State Mill and state-owned Bank of North Dakota, both of which served to address the theme of economic disadvantage. The “too-much mistake” was that more towns, farms, schools, roads, colleges, churches, and governmental institutions were established than could be supported — all requiring adjustment, Robinson’s last theme.

More about the man: Elwyn B. Robinson, 1905-1985

Elwyn Burns Robinson, University Professor Emeritus of History at UND and a noted state historian, was born on a farm in Ohio and earned degrees from Oberlin College and Case Western Reserve University in Cleveland. In 1935, he was invited to join the UND faculty by Libby. He wrote and presented a series of popular radio talks titled “Heroes of Dakota.” This led to writing History of North Dakota, which even today is considered one of the best state histories in the nation. He remained active after his retirement in 1970.

Elwyn Robinson lectures to his last class in the Department of History before retiring from the UND faculty in 1970.

Now - Updating a Classic Kim Porter takes over where Robinson left off, all the way into the new millennium

It needed to be done, said Kim Porter, professor of history, about her book, North Dakota: 1960 to the Millennium. It started when one of her North Dakota history students said her grandfather may have been a North Dakota governor.

“Turns out it was her great-grandfather, and he was a senator,” Porter said. She teaches courses in North Dakota history, and knew an update was needed for the classic History of North Dakota, which is still used in state history courses across the state. Elwyn Robinson’s history, published in 1966 and still in print, essentially ended in 1950, and there was no current state history.

“North Dakota is their home,” she said of her students. “Their grandparents read the same history book that students do today. They need to continue the history with current names and faces.”

North Dakota’s role has changed, Porter said. When Robinson’s history ended with the 1950s, the Cold War was ongoing, the state had no interstate highways, no missile stations, and no oil boom. Garrison Dam was not yet built, and televisions were a luxury. Today, politics have changed, North Dakota has its first woman senator, and it is the only Great Plains state that is growing.

Porter, who grew up on a farm in Iowa, was a bit nervous about being seen as an outsider. But Robinson himself was an Ohio native, and Porter has been in the state for 18 years, longer than most of her students have been walking. She joined UND in fall of 1996, “just in time for the 1997 flood,” and was attracted to the position because it was the only listing with “rural” and “agriculture” in the job title. “I understand what a piece of ground means and feel a connection to tradition.”

Porter’s book connects North Dakota to the nation and focuses on politics, the economy, weather, and interesting aspects of the state, such as the “Zip to Zap,” the Poppers and their Buffalo Commons proposal, and more.

“Focusing on a box of dirt is boring,” she said. Through feast and famine, boom and bust, flood and drought, the book details North Dakota and its connection to national politics and the larger world with a clear and affectionate eye.

“There’s nothing flat about North Dakota except the Red River Valley,” she said.

Porter pursues other projects in addition to North Dakota history. She is currently working on a Grand Forks community oral history in which she interviews community elders, and is kicking off an oral history of World War I veterans by interviewing their children. She recently completed an oral history of the Synagogue in Grand Forks, which is now on the National Register of Historic Places, and is working on a book about Henry Field, a seedsman from Iowa who founded Field’s Seed and Nursery Catalog.

“People don’t write books anymore like Elwyn Robinson did,” she said about the 20 years Robinson spent writing the book. “Academics are expected to produce more.”

And Porter’s book already needs a new chapter, she said. Times are changing so fast that it’s out of date as soon as it’s printed.

“If this is where you want to be, you can make your story here,” she said. “You become a person rooted in something greater than yourself.”

Kim Porter: "There’s nothing flat about North Dakota except the Red River Valley."

Then & Now: UND Research on the National Map

UND Discovery Magazine - Mon, 2013-12-09 09:00
Then - Laying the Foundation for a National Reputation Robert Nordlie’s research helped put his department and UND “on the map” nationally and across the globe

For 38 years, Dr. Robert Nordlie was dedicated not only to research at the University of North Dakota, but also to the success of the Department of Biochemistry & Molecular Biology.

Fueled by the same National Institutes of Health grant for 35 years, Nordlie brought international recognition to UND with his research of glucose-6-phosphatase, an enzyme that regulates blood glucose levels. His research has proven helpful in the study of diabetes, cancer and other diseases.

Before graduating from UND with a master’s degree in 1957 and a Ph.D. in biochemistry in 1960, he received his bachelor’s degree from St. Cloud State University in 1952. It was during his postdoctoral research fellowship in Dr. Henry Lardy’s Institute for Enzyme Research at the University of Wisconsin-Madison that Nordlie first pursued the topic he would spend the next four decades researching:  glucose-6-phosphatase.

“One of the great happenings of my life was going to the Institute for Enzyme Research and working with Dr. Henry Lardy,” Nordlie said.  “Dr. Lardy was interested in gluconeogenic enzymes, and that is how I got introduced to carboxykinase and the biosynthetic activities of glucose-6-phosphatase.”

In 1962, Dr. William Eugene Cornatzer, the founder of the UND Department of Biochemistry and chair of the department from 1951 to 1983, enticed Nordlie to come back to his alma mater as a full professor straight out of his postdoctoral research.

“Becoming a full professor straight out of a post-doc is and was almost unheard of,” said Dr. John B. Shabb, associate professor in the UND Department of Basic Sciences, who was hired by Nordlie in 1992.  “Dr. Cornatzer knew this was somebody who was going to make a difference.”

“Dr. Cornatzer was a very ambitious man and he wanted to set up a research-oriented facility,” Nordlie said. “Some people made fun of him, but we put North Dakota on the map nationally and internationally. He supplied the drive; I supplied the ideas and the research.”

Though Nordlie retired 13 years ago, his passion for enzymes is still evident.

“I am personally delighted, at age 83, with the veritable explosion in the glucose-6-phosphatase field. There is great potential there for clinical applications,” wrote Nordlie in his then-and-now review of his research, A Retrospective Review of the Roles of Multifunctional Glucose-6-Phosphatase in Blood Glucose Homeostasis: Genesis of the Tuning/Retuning Hypothesis. His publication outlines the transformation of his field from being solely biochemistry to both biochemistry and molecular biology.

Nordlie took over as the chair of biochemistry when Cornatzer retired in 1983. He proposed renaming the department as “Biochemistry & Molecular Biology” and brought the first three molecular biologists to the University.

“That’s the interesting thing. Even though he himself didn’t want to make that change, he recognized the need for the change in the department and he went out and did it,” said Barry Milavetz, a professor in the UND Department of Basic Sciences and associate vice president for research development and compliance. “That’s real leadership.”

Milavetz worked alongside Nordlie after being hired by him in 1986.

On July 1, 2013, the UND Department of Biochemistry & Molecular Biology changed to the UND Department of Basic Sciences as the School of Medicine & Health Sciences merged the basic science departments.

“Bob retired 13 years ago, and even though the department no longer exists as an independent entity, his impact on basic science research and education at UND persists.”  Shabb said. “Five current faculty members in the Department of Basic Sciences were hired and mentored by Bob Nordlie.  They include a Chester Fritz Distinguished Professor, Roxanne Vaughan; an associate vice president for research, Barry Milavetz; and the last chair of the Biochemistry & Molecular Biology Department, Kathy Sukalski.”

His impact on the department went beyond the research.

“He was an outstanding lecturer for medical students,” Shabb said. “I still go over to Altru for a doctor’s visit, and when they find out I am a biochemist, they say, ‘Oh I remember when,’ and they will mention a specific lecture from 30-plus years ago given by Dr. Nordlie.”

Nordlie spent 38 years teaching metabolism and was named the UND School of Medicine and Health Science’s first James J. Hill Research Professor, a position that was funded by the family of railroad executive James J. Hill.

He also published more than 130 research papers around the world in publications such as The Journal of Biological Chemistry.

“He spoke well with students and he spoke well with faculty,” said Sukalski, associate professor in the Department of Basic Sciences. “He really wanted to see the faculty he hired succeed.”

“He has influenced me not only from the scientific perspective, but he also taught me how to run a meeting, how to interact with people, and how to be diplomatic,” Milavetz said. “For an administrator, those qualities are important.”

The former UND Department of Biochemistry & Molecular Biology won the University Outstanding Research Award twice under Nordlie’s administration.

“It was the type of people that were hired and the environment in which they were placed that led to the success of the department,” Sukalski said.

Now - Genes of Our Fathers, Disease of Our Children A UND team scores a major award to study the role of epigenetics in human health – past, present and future

Roxanne Vaughan: This grant will support young investigators, enhance programs across multiple disciplines, and elevate the research capacity of the University.

Epigenetics — the hard science behind the mystery of whom each of us becomes — is gaining lots of international attention.

In fact, so much that the federal government is putting a lot of cash behind programs that dig into the elusive mystery of this relatively new field.

The National Institutes of Health (NIH) recently awarded the University of North Dakota $10.5 million in a five-year grant to support an Institutional Development Award (IDeA) Center of Biomedical Research Excellence (COBRE).

The question of the epigenetic role in diseases is uppermost on the horizon for this new UND COBRE team.

“Abnormal epigenetic regulation has been implicated in a variety of human diseases,” said Joyce Ohm, a core member of the new center that investigates, among other things, the abnormal epigenetic silencing events in the initiation of human cancers. “Those diseases include cancer, obesity, diabetes, infertility and neurodegenerative disorders such as Alzheimer’s disease or Parkinson’s disease.”

UND researchers are working to understand the bases for these diseases and how epigenetics may play a role in the onset of diseases in future generations, and to develop new strategies for treatments or preventions.

Ohm, an assistant professor of biochemistry and molecular biology, and her epigenetics research colleagues note, an individual’s overeating or cigarette smoking or cancer today might be a result of what his or her grandparents did and might have an effect on his or her children and grandchildren.

Learning more about how that all happens is the key to UND’s new COBRE.

Epigenetics relates to the biochemical machinery at the cellular level that switches specific genes on — or doesn’t — affecting what each of us does: for example, what we choose to eat, how we sleep, how we get sick, whether we get cancers or Alzheimer’s, and how we express a whole range of other behaviors.

“This grant will significantly expand epigenetic research at UND by instituting a variety of programs that will support young investigators at early stages in their careers, establish core facilities and purchase major equipment, and assist with faculty mentoring and development,” said Roxanne A. Vaughan, principal investigator of the COBRE and a Chester Fritz Distinguished Professor of Biochemistry and Molecular Biology in the UND School of Medicine & Health Sciences. “Together these programs will enhance research across multiple disciplines and elevate the research capacity of the University.”

As an established biomedical researcher, Vaughan’s participation in the grant proposal was crucial. The NIH expects that the principal investigator for a new COBRE must be able to ensure high-quality research and have the experience to administer effectively and integrate all components of the program.

Vaughan will help support the projects of the new center’s core team members, including Ohm, Lucia Carvelli, assistant professor of pharmacology, physiology and therapeutics; Archana Dhasarathy, assistant professor of biochemistry and molecular biology; and Sergei Nechaev, assistant professor of anatomy and cell biology. The team comprises researchers who are early career investigators or those with established research programs in other fields whose research has led them to the exciting area of epigenetics.

The new center expands UND’s ongoing epigenetics research program, which includes a group of interested scientists from several different departments and colleges, as well as the U.S. Department of Agriculture Grand Forks Human Nutrition Research Center. The group has been meeting regularly on campus since 2010.

Then & Now: Music

UND Discovery Magazine - Mon, 2013-12-09 08:50
Then - Renaissance (music) Man

Gary Towne has searched through more than 60,000 pages of Latin documents while investigating music and institutions in medieval and Renaissance Bergamo, Italy.

As a musician, historian and professor, one faculty member’s research of the musical past is an octave above the rest.

Gary Towne, professor of music, has already published an extensive first volume (Masses) of the Collected Works of Gaspar de Albertis, and now he’s working on a second volume about the famous Renaissance composer from Bergamo, Italy.

Towne doesn’t just waltz in to his publications; he goes all-out.

He has reviewed and researched more than 60,000 pages of Latin documents to find about 6,000 significant ones during seven visits to Bergamo.  Cataloguing is still in progress, having reached about 4,500 documents for a separate project he’s working on: a book titled Music and Musical Institutions in Medieval and Renaissance Bergamo.

His six research visits, totaling more than a year, were funded by grants from the Gladys Krieble Delmas Foundation and a Fulbright grant.

Towne currently is working on a volume of motets by Albertis, with two more volumes planned on Vespers and Holy Week music to go.

Albertis, a priest, wasn’t just a virtuoso; he was an innovator. That’s why Towne chose him. Towne was intrigued that Albertis was one of the first composers ever to write polychoral music. He was also one of the first to have his portrait painted, which at the time was a rarity.

Towne discovered Renaissance music as a child.  After hearing a Renaissance work in the background of a Disney program, he was consumed with that music.

“Nothing else has the same appeal for me,” Towne said.

It is with this passion that he has written 12 articles about Bergamo on topics ranging from a 1519 organ contract for the Bergamo cathedral to pedagogical philosophy in 17th-century Spain.  Towne also has the book in progress about music in medieval and renaissance Bergamo, and is continuing work on Albertis’ collected works.

Towne’s credentials are impressive, with a bachelor’s degree in music theory from Yale and a doctorate in musicology from the University of California, Santa Barbara.

His experience has enabled him to teach courses in music history, theory, world and American music, and interdisciplinary courses in the fine arts, the Italian Renaissance and early America.

Now - Pushing Boundaries in Musical Expression

Step off the beaten musical path and you’ll find Michael Wittgraf producing a musical composition without a single instrument, just Wii remotes and a laptop.

This is electronic music, and it’s what sets Wittgraf apart from the other music professors at the University of North Dakota.

Considered an innovator in the field, Wittgraf loves to experiment with different music software and equipment to provide audiences with a truly unique experience.

No wonder he was chosen as the first music professor at UND to be named a Chester Fritz Distinguished Professor, the school’s highest faculty honor.  He also serves as chair of the Department of Music.

Using both fixed media and live electronics, Wittgraf loves to interact with an audience and leave them speechless.

This past spring, while performing on tour in Japan and China with the Red River Trio (comprising a cellist, pianist and violinist), Wittgraf was able to give his Asian audiences a taste of his eccentric musical muse.

Wittgraf’s music has made its way to other parts of the globe as well, including presentations in Europe and Australia.

Apart from electronic music, Wittgraf plays bassoon, piano, organ and electric bass. His compositions span multiple genres, including solo, chamber, orchestral, band, choral, and, of course, electronic.

Wittgraf earned his master’s in music theory and composition from the University of Minnesota and his doctorate in music composition from Northwestern University.

Perhaps a bit surprising is the bachelor’s degree in mathematics that he earned from Carleton College.  But Wittgraf observes that having a firm grasp of arithmetic actually helps him in the digital world of electronic music.

“I had an aptitude for math, but a passion for music,” said Wittgraf.

About four years ago, Wittgraf decided to compose electronic music almost exclusively. But he’s not one to push the genre onto others, especially students.

For Wittgraf, one of the most rewarding experiences is when he can sit back and watch students perform and find their own musical niches.

He said, “I’ve been brought to tears more than once by student performances.”

Then & Now: Pushing the Frontiers

UND Discovery Magazine - Mon, 2013-12-09 08:40
Then - The "Deep Blue Sea" of North Dakota Research at landlocked UND yielded discoveries about high-pressure environments

The University of North Dakota wasn’t the obvious choice to conduct deep-sea research.

The irony is inescapable, as the University is roughly 1,500 miles away from the nearest ocean. Rugby, N.D., just 150 miles to the west, has a stone cairn marking the geographical center of North America. But UND’s geography was irrelevant for faculty in engineering and medicine who looked to expand their research capabilities in the 1960s.

They submitted proposals to the U.S. Department of Defense after the creation of “Project Themis,” a program established to develop centers of excellence at universities. Their second proposal was approved and, starting in 1968, the University received capital to construct a new kind of lab. It was known as the “Man-in-the-Sea” project.

Funded by the Office of Naval Research for $2 million — a big amount today and even bigger then — the UND High-Pressure Life Laboratory was the only one of its kind in the western world. The 40-foot-long, 20-foot-wide, and 9-foot-high structure in Upson Hall consisted of two 7-foot spheres joined by a passageway and a gate valve. Each sphere had seven sub-chambers — animal living chambers — where atmospheric pressure was regulated by an IBM computer.

During the dedication of the laboratory on Nov. 30, 1973, U.S. Navy Rear Adm. M.D. Van Orden noted that although humans have walked on the Moon, the oceans on our own planet were still a mystery to us. The Man-in-the-Sea project was a giant leap forward.

“There is no other laboratory like this elsewhere in the world that can do the type of research that will be conducted here,” said Van Orden.

Thomas K. Akers, a Brooklyn, N.Y., native and UND physiology and pharmacology professor, became the director of the Man-in-the-Sea project in 1972. Akers, a Navy veteran and founding member of the North Pacific’s chapter of the Underwater Medical Society, found that humans are fragile under extreme pressure.

“Many of the physical laws we’ve always accepted don’t seem to hold in a high-pressure environment, and we are just beginning to discover some reasons why this is so,” Akers told the Grand Forks Herald.

During the lifespan of the project, tests were run on the animals’ respiration, oxygen toxicity, nutrition, bone and calcium metabolism, circulation, reproduction, drug metabolism, and renal function. The data collected helped researchers understand the effects of high atmospheric pressure on humans at sea depths of 1,300 feet. Naval Research hoped the results would eventually lead to humans having the ability to harvest food and resources off the continental shelf, an undersea plateau that forms 18 percent of Earth’s total area.

Keeping humans healthy at those depths is challenging. It centers on finding the minimums and the maximums. Under pressure, nitrogen, argon and other gases become so dense it’s hard to breathe. An interdisciplinary team of UND researchers began substituting nitrogen in favor of helium, which was less dense under pressure. They learned nitrogen is an essential element, a fact they didn’t know before the study.

Researchers had another good day at the office when they returned a group of lab rats to normal atmosphere after 84 days at 20 times the normal atmospheric pressure. The pressure maintained during the experiment simulated pressure below 660 feet of sea water — near the maximum depth of the continental shelf. It nearly tripled the longest span a human had spent in those conditions at the time.

Though breakthroughs like these provided the Navy with essential information, the Man-in-the-Sea project had a shelf life.

With rising equipment costs, once the Man-in-the-Sea project met all original objectives, it ended in 1977. The large pressure chamber was dismantled. The seven-foot spheres were given to the UND Park District and became playground equipment for children growing up far from any ocean.

Akers drove past the new-use playground spheres every day on his way to work.

“They remind me of the good days,” he told the Herald. “They were busy, long days, but it was lots of fun. It was one of the largest interdisciplinary projects ever done at UND, and the sense of teamwork we had was wonderful.”

Editor’s note:  Thomas Akers retired from the UND faculty in 1991.  In addition to his teaching and research accomplishments, he also was recognized as an artist.

Now -The Moon and Beyond, Right on the Campus
(cover story) UND puts a total planetary exploration system to the test

Students Travis Nelson (left), Tim Buli and Erica Dolinar spent 10 days in a pressurized, inflatable “habitat” designed to simulate a surface exploration mission on the Moon or Mars. Funded by NASA, the trial tested life support and other engineering systems and received considerable media attention.

A recent international test of three spacesuit systems locked in the University of North Dakota (UND) as a key player in planning for future long-term missions in space.

UND was the only university on the planet invited to participate in the European test program held in October. UND’s Department of Space Studies team flawlessly showcased its ingenious, team-built NDX spacesuit system under the glare of media spotlights.

“We specialize in spacesuits for surface exploration,” said Pablo de León, an aerospace engineer from Argentina and director of UND’s Human Spaceflight Laboratory, all part of the Space Studies program in the John D. Odegard School of Aerospace Sciences. “They’re specifically enhanced for locomotion: for walking and for manually manipulating objects, tools, etc., on a planet’s surface. We want to improve mobility, to allow freer walking and working on a planet with lower gravity than Earth’s.”

The recent European test was part of an ongoing international effort to prepare for an eventual human expedition to Mars.

Pablo de León, director of UND’s Human Spaceflight Laboratory, watches as Space Studies graduate student Josh Borchadt tests the suitport mechanism that supports the NDX-2AT spacesuit on a “rover” simulator. The system would use airlocks to eliminate or minimize the intrusion of surface dust, an issue encountered during the Moon missions of the 1970s.

Well suited

De León’s lab is the home of the NASA-funded NDX Planetary Exploration System.  But we’re not just talking spacesuits; NDX is a whole system for the surface exploration of planets such as Mars.

“We’re designing, planning and building the whole system, including the suits, the inflatable habitat, the air locks and rover,” de León said. “We developed the research infrastructure to simulate an entire planetary base scenario, and it puts us in the forefront of lunar and Mars mission planning.”

De León, who spent many years in industry working on spacesuit design and who has penned several books about manned spaceflight, says UND is uniquely qualified for the work ahead.

“We have in place the analog infrastructure that will allow planners of long missions to do tests right here at UND,” he said.

The UND NDX team set up a trial run this fall, putting three specially selected students into the system’s pressurized inflatable habitat for 10 consecutive days. The trial, funded by NASA, was designed to simulate a surface exploration mission on the Moon or Mars. It included tests of the habitat’s life support and other engineering systems.

Researchers also designed the trial to see how well the system components, including the habitat, rover, spacesuits and airlocks, worked together. This was a prelude to a much longer trial scheduled for spring 2014. De León added that NASA’s Jet Propulsion Laboratory, which has been involved in just about every U.S. space mission, recently sent other experiments to try out in UND’s pressurized, inflatable habitat.

De León foresees that UND will be testing and working a lot more with NASA, which has funded his team’s work, and with the space industry and international partners to make these missions a reality.

“The idea is that as a university, we’re going to create useful knowledge,” de León said. “That includes producing prototypes such as our NDX system that are useful to NASA and the companies that will actually build the suits.”

Proof of UND’s influence in the spacesuit system sphere is a recent second edition of U.S. Spacesuits, a book by Kenneth Thomas. He is a historian and engineer at Hamilton-Sundstrand (HS), one of the two primary builders of U.S. spacesuits. In that book, one of UND’s NDX suits is prominently featured in photos and text.

Space Studies graduate student Tiffany Swarmer puts one version of UND’s NDX spacesuit through an exercise to demonstrate its flexibility and range of motion.

No ordinary spacesuit

One of the key elements of equipment for a future human expedition to Mars will be a spacesuit that allows astronauts to roam the surface. Martian explorers will face a bitterly cold, dusty environment with a thin atmosphere of mainly carbon dioxide. They’ll have to rely on their spacesuits to provide oxygen to breathe and a comfortable temperature, pressure, and atmosphere in which to work.

Then there’s the mobility issue, de León said, comparing the NDX suit with the current day “zero-g suit” worn by astronauts doing spacewalks while tethered to the International Space Station (ISS).

“The ISS suits are almost immobile from the waist down because you don’t need any walking capabilities in that environment, even though it’s called a space ‘walk,’” de León said. “All they have to be able to do is attach their feet into a foot restraint located at various points on the ISS.

“What we try to do is the inverse of that: we aim to develop suits where you can use your legs and arms in order to facilitate your work on a planet’s surface.”

In addition, de León said that the NDX team is designing and building suits that can be serviced and repaired on the planetary surface.  Most of the suits developed so far are Earth-servicing only, designed to be used in low-Earth orbit, such as on ISS, and then taken back to Earth after a couple of space walks.

“But for a mission to Mars, which is expected to last at least three years, you can’t take your suits back for repairs or maintenance. You have to be able to do that right where you are — on Mars,” he said.

An interesting place

De León sees space exploration, including a trip to Mars, happening relatively soon.

“But we’re not going to do it one country at a time,” he said. “It’s not necessarily going to be done by the United States all by itself. Because of the cost and complexity of a crewed mission to Mars, you’ll see a consortium of partners that have already been successful in space, working together to get to that goal.”

De León sees the NDX system as a key player in the development of future space missions.

“This all puts us in a very interesting place,” he said. “We have a starting point to become a university known globally for having a unique system that we can offer organizations such as NASA.”

De León said that for students on his team — both undergraduates and graduates — the work is highly participatory.

“Ultimately, it’s about our students. Because we’re very hands-on oriented and because I have extensive experience in the space industry, I believe that our students should not just be working from a stack of texts and papers,” said de León. “Our students come to us from all over the world because they’re excited about the research we’re doing here.”

Making Sparks to Ignite a Passion for Science

UND Discovery Magazine - Mon, 2013-12-09 08:30
UND physicist Nuri Oncel looks for connections to encourage prospective students to discover new interests within themselves

Art teacher Betsy Thaden and Nuri Oncel hold paintings created by students in her class at Red River High School in Grand Forks. Oncel provided images of atoms and molecules to spur the students’ creative instincts — and perhaps more curiosity about science as well.

For ambitious teenagers looking to shape the world we live in, a career in science is a perfect fit.

That’s what University of North Dakota physicist Nuri Oncel found as a boy growing up in Konya, Turkey, in the 1990s. An early interest in math and science sparked his eventual career in physics — a natural fit that has opened doorways to a world of discovery.

“In high school, I had a great math teacher,” Oncel said. “After taking a couple semesters of his classes, I realized I should either be a mathematician or physicist. I love how your brain actually operates when you do mathematics. I loved the magic of that.

“That teacher knew how to teach. He knew how to challenge the students and help students understand the concept:  the real meaning of the mathematics.”

Today, Oncel is the one doing the inspiring, getting local high school students to dabble in real research in hopes they might one day consider careers in science.

Supported by a National Science Foundation grant, Oncel is researching advances in nanotechnology that could make electronic devices lighter, cheaper and more powerful.

“One day, we will be using individual atoms to make a device,” Oncel said. “At that point, classical physics won’t be enough. Devices will be working under the laws of quantum physics. Then, everything we know of will be different.”

As part of the research, he is reaching out to high schools and tribal schools across the region to get young people involved.

In one initiative, Oncel is presenting images of atoms and molecules to local high school students; they, in turn, take inspiration from the images and create works of art for exhibition.

“I can talk about quantum mechanics and how interesting this nano stuff is, but it won’t appeal to all of the students.” Oncel said. “I believe that if we use art to express science, it will be more attractive, because there is a human connection to that.”

“After creating art or looking at a friend’s artwork, maybe one of the students will choose to become a scientist. Then I’m happy. Then the project is a success.”

Betsy Thaden, an art teacher at Red River High School in Grand Forks, N.D., said the images provide her students with meaningful learning opportunities that link art with real-world applications.

“The experience gave them insight into new possibilities and exposure to a science they may not have known about,” Thaden said. “It also opened their eyes to how the arts align and are connected to other curricular areas.”

Oncel hopes the art also will attract attention in local communities when it goes on display; he wants as many people as possible learning about the innovative research happening at UND.

Oncel knows that some students write off physics as a possible major, thinking that a physicist mainly works at a desk and tackles complicated equations. However, not all physicists work that way.

“In the lab, we design and build special instruments to study physics of nanostructures. An important part of the work involves using wrenches, nuts and bolts — really basic instruments. It’s very hands-on work.” Oncel said.

Oncel is also reaching out to American Indian communities.

“You don’t find a lot of American Indian students in physics, chemistry or mathematics,” he said. “I’m a physicist and I’m kind of worried about that.”

Oncel invites American Indian teachers and students to get involved. He realizes he can work with only a limited number of Native American high school students in the lab.

“When I work together with a high school teacher on a research project related to nano science, I actually reach out to all the students in that school.” Oncel said. “Because the teacher carries that know-how back to the classroom, and that increases our chance to have a student major in science.”

And what the influence of a good teacher can do is something that Oncel knows very well.
