Academy of Science and Engineering Inductees
The Swenson College of Science and Engineering inducted five new members into the Academy of Science and Engineering on Friday, October 8, 2010:
Dr. Stephen Brand, BA Geology 1971
Mr. Keith Erickson, Bachelor of Computer Engineering 1987
Mr. Kurt Heikkila, MS Chemistry 1979
Lt. Gen. Samuel Helland, USMC, BS General Sciences 1973
Dr. Bruce Warren, BS Zoology 1949
DR. BRUCE HUNTINGTON WARREN
2011 Biology Inductee
Academy of Science and Engineering
Dr. Bruce Warren graduated with a B.A. in Zoology from UMD in 1949. He and his future wife, A. Jane Berry, attended UMD together and were married after Bruce graduated. Jane finished her degree at the University of Minnesota graduating magna cum laude. Bruce completed stints in China and the Pacific with the Marines in WWII and was later chief of the USAF Aerospace Medicine Weightlessness Section. His work with weightlessness led him to become an aerospace research flight surgeon, earn board certification in aerospace medicine, and conduct research he called, “More fun than work.” Before the first manned space launches, Bruce studied the physiological effects of weightlessness by flying zero gravity parabolic flight maneuvers in supersonic jet fighters. When the U.S. entered the conflict in Vietnam, the focus of Bruce’s research changed. He flew on combat aeromedical evacuation flights to study lifesaving equipment. Back in the States as commander of the USAF Epidemiology Laboratory in San Antonio, he became involved in the early studies of drug addiction in Vietnam veterans and the relatively high rate of attrition among new Air Force recruits. These studies, along with Bruce’s interest in brain biochemistry and human behavior, led him to return to school to become a psychiatric medical doctor. He did his residency at the Wilford Hall USAF Medical Center in San Antonio. Five years after starting his residency, he became chairman of the Psychiatry Department, where he stayed until his Air Force retirement. Following that retirement in 1980, he joined the faculty of the University of Texas Health Science Center at San Antonio, where he continued his career in research, teaching, and clinical practice.
Summer 2010 NEWS
Biological Discovery in Woods Hole (BDWH) Program
The 2010 Biological Discovery in Woods Hole program undergraduate students, from left: Samantha Lindemann, Kelly Harrington, Kurt Isaac-Elder, Cassandra Childs, Tim Eisen, Sophia Booth, Allan Augillard, Chelsea Connelly, Shavonn Smith, and Solymar Rivera.
Allen Mensinger, associate professor, UMD Department of Biology, co-founded a new undergraduate research program at the internationally renowned Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts. Along with Paul Malchow, a faculty member at University of Illinois, Chicago, Mensinger developed the Biological Discovery in Woods Hole (BDWH) program, pairing undergraduates and faculty mentors for summer research.
In this inaugural year of the program, Samantha Lindemann, biology major at UMD, joins nine other undergraduates from U.S. universities. Each student is paired with MBL scientists as research mentors at this international center for research and education in biology, biomedicine and ecology. The undergraduates join the more than 470 advanced graduate students and post-docs at the facility.
Mensinger is Lindemann's mentor. She was involved with research at UMD before coming to the MBL. However, Mensinger says that she is experiencing a radical change in the “scale” of her research, switching her focus from small zebrafish to one meter-long smooth dogfish.
"BDWH received over 120 applications for the program's ten slots," said Mensinger. "Samantha Lindemann's selection provides further proof that UMD's upper echelon biology majors are nationally competitive. She has been able to transition seamlessly into a very high-pressure research environment and is performing neurophysiology and neuroanatomy experiments on both toadfish and sharks. Her future plans are to apply to Ph.D. programs in the fall and the BDWH program already has allowed her to interact with potential graduate school mentors." Lindemann was recently awarded the UMD Mowbray Scholarship in the Biological Sciences.
Lindemann is enjoying her summer in Woods Hole. "We are immersed in science. It's discussed not only in the lab, but at breakfast, during lectures, and at receptions; science is basically the main topic of conversation," she said. "I can see how much cooperation and collaboration goes into biological research. For example, if I have a question about fish histology, I can walk up the stairs and talk to Dr. Steve Zottoli. If I want to talk about microbial oceanography, I can walk across the street and talk to Dr. Julie Huber."
The students are receiving hands-on contact with the high tech and not-so-high-tech devices needed to conduct experiments. "There is a lot of fancy equipment, but there is also a lot of equipment that scientists have designed and made themselves," Lindemann said. "Sometimes we have to get creative. One of my favorite items in the lab is a five gallon pail with hash marks for 1 to 14 liters marked on the side. This bucket makes measuring water to anesthetize a shark or transport a toadfish much easier. I never would have thought I would become so attached to a five gallon pail."
Lindemann said she is extremely grateful for the opportunity to participate in the program. "Dr. Mensinger really gave me an incredible opportunity, not only to do research this summer, but also to be immersed in the mecca of science that is MBL," she said. "I am honored that he had enough confidence in my academic abilities to bring me to the MBL."
In the BDWH program, promising juniors and seniors in college are provided with research experiences that are only available at a few institutions. Students and investigators tackle projects in molecular and cell biology, neurobiology and behavior, physiology, developmental biology, ecology, and evolutionary biology.
In addition to conducting research, students attend events several times a week where they meet and hear established researchers speak about life as a scientist. Discussion topics include graduate school applications, choosing a career path, and ethics in science. Students also frequently participate in field trips and group activities. The BDWH students will present their research findings at a symposium at on August 19.
The program is funded by a National Science Foundation – Research Experiences for Undergraduates (NSF REU) grant. Mensinger and Malchow say that they are indebted to Marine Biological Laboratory staff and administration for their support of the establishment of the BDWH program. Mensinger and Malchow have long been dedicated to supporting undergraduate research, and they hope BDWH opens doors for students.
The 2010 Biological Discovery in Woods Hole students are: Allen Augillard, Xavier University; Sophia Booth, Colorado College; Cassandra Childs, Wittenberg University; Chelsea Connelly, Valdosta State University; Tim Eisen, Brown University; Kelly Harrington, Bridgewater State College; Kurt Isaac-Elder, Howard University; Samantha Lindemann, University of Minnesota, Duluth; Solymar Rivera, University of Puerto Rico; and Cayey Shavonn Smith, Ursinus College.
UMD held grand opening ceremonies June 22 for the exciting new state-of-the-art sustainable Bagley Classroom located on the 55 acre Bagley Nature Area adjacent to the UMD campus. Because of the wide variety of forest and aquatic ecosystems, the Bagley Nature Area is an outdoor teaching laboratory almost without parallel on any other campus in the Unites States.
Amazing in its far-reaching sustainable design, the new Bagley Classroom is designed to be a LEED Certified PLATINUM Award building which will serve as a vital learning tool and a model of sustainable design and construction for all of Northern Minnesota.
Designed by internationally noted Duluth architect, David Salmela, with construction and landscaping done entirely by the staff of the UMD Department of Facilities Management, the 2,000 square foot classroom rests quietly in the woods covered in zinc siding with a green veil of vegetation on the roof. It sits lightly on the earth, both environmentally and visually. The interior design is warm and inviting, with reclaimed and regional timber beams and local wood paneling. All exposed materials are maintenance-free. The south wall is comprised of glass, maximizing views of Rock Pond and the surrounding forest, while providing passive heating in the winter. Large operating windows on the east and west walls also provide views and natural ventilation. The lighting system will be used minimally because all occupied spaces will have abundant daylight.
While nationally the building sector contributes between 40% and 50% of all carbon emissions in the United States, the Bagley Classroom is designed to slash energy consumption as a super-insulated and airtight building. The passive solar heating will supplement the building’s heating needs while a high efficiency heat recovery ventilation unit will continuously provide fresh air. It is anticipated that the on-site grid-connected solar photovoltaic system will provide as much energy as the building uses. Most wastewater will be treated on-site through the use of modern looking composting toilets.
Primarily used by the UMD Department of Biology for science instruction ranging from general biology labs to the study of ecosystem ecology, ornithology and entomology, the Classroom will also be used for environmental studies, geography studies, teacher education, outdoor management/operations studies, art/drawing, recreational outdoor programs, and early childhood learning activities.
It is informative to note some distinct characteristics of the Bagley Classroom to qualify it for the LEED Certified PLATINUM Award.

From Stephanie Guildford, assistant professor, Department of Biology. Although Lake Superior has excellent water quality relative to the other North American Great Lakes, lake trout have surprisingly high concentrations of PCBs. In this survey of 23 lakes, including Lake Superior, extending from northwestern Canada to the southern extreme of lake trout distribution, lake area and latitude accounted for most of the variation in PCBs. Trout in smaller and more northerly lakes had greater access to productive benthic littoral habitats for feeding and had lower PCB concentrations compared to lake trout in larger more southerly lakes where feeding was more restricted to the offshore, pelagic habitat. Guildford, S.J., Muir, D.C.G., Houde, M., Evans, M.S., Kidd, K.A., Whittle, D.M., Drouillard, K., Wang, X., Anderson, M.R., Bronte, C.R., DeVault, D.S., Haffner, D., Payne, J., Kling, H.J. 2008.
