A Message from the Department Chair

Shekhar Joshi Portrait

What a year (or two)!
Greetings from the Department of Biological Sciences at Michigan Tech! It gives me great pleasure to share this bi-annual report of various ongoing activities and exciting accomplishments by our faculty, staff, and students during Spring 2020-Fall 2022.

In the spring of 2020, I was on sabbatical for one semester. The news of a possible COVID-19 pandemic broke out in February 2020 when I was in New Zealand. I immediately returned home, and Michigan Tech moved to a virtual mode of education in March 2020. Our faculty swiftly switched to this new mode in about a week, and all lectures and even remote labs became operational without severely affecting our educational mission. The semesters that followed were full of challenges, but I am glad to report that we somehow weathered this unprecedented storm, and the fall 2022 semester feels almost back to normal. The research labs were closed for over a semester in 2020, but as you can see from this report, research rebounded very quickly. The folks at the Biology department were also closely involved in setting up a COVID-19 testing lab, a unique undertaking as highlighted in this newsletter later on. Our faculty, staff, and students brought in over $9.9M in funding during this period and published over 90 peer-reviewed publications. The teaching mission has remained as strong as ever, with faculty and others winning state-wide and university-wide accolades. I hope you will enjoy reading about these and other highlights in this newsletter.

We would love to hear from you. Please call my office at 906-487-2738 or email me at cpjoshi@mtu.edu to let us know how you are doing. Please feel free to stop by Dow 740, and we would be happy to show you our research labs and newly upgraded teaching labs. The campus and overall surroundings are also looking very beautiful now, so please come back to the Keweenaw very soon!

She earned her BS in Marine & Freshwater Biology at the University of New Hampshire and her MS in Marine Science from Hofstra University. She earned her Ph.D. in Environmental Sciences from the University of Windsor in 2012. Her research aims to understand how habitat use and foraging decisions and environmental regimes, such as altered salinity and temperature gradients related to climate change, shape the distribution of predators and prey and how those interactions structure aquatic ecosystems.


John Durocher Portrait

In the Fall of 2020, associate professor John Durocher joined Purdue University Northwest as Nils K. Nelson Associate Professor of Integrative Human Health. At Michigan Tech, John did extensive work in the fields of applied human physiology and exercise physiology. He also taught Anatomy and Physiology, and human pathophysiology courses and was nominated for the teaching award. Our best wishes for his new appointment.

Ebenezer Tubman Portrait

Associate professor Ebenezer Tumban moved to Texas Tech University, School of Veterinarian Medicine, in the Fall of 2020. Dr. Tumban is a molecular virologist and vaccinologist, and in the past, he conducted research studies aimed at understanding the molecular determinants of arboviruses (such as dengue and Langat viruses) mode of transmission. He was also nominated for the teaching award at Michigan Tech. We wish him all the best in his new endeavors.

Charles Kerfoot Portrait

Professor W. Charles Kerfoot retired at the end of Spring 2020. Dr. Kerfoot’s distinguished research career in the freshwater ecology of the Great Lakes spans over 47 years. At Michigan Tech, Dr. Kerfoot has served as the Director of the Lake Superior Ecosystem Research Center and Remote Sensing and Ecosystems Research Institute. Dr. Kerfoot received several accolades, such as Michigan Tech’s Distinguished Faculty Research award in 2013, Lifetime Achievement Award by International Association for Great Lakes Research in 2014, and the Eugene P. Odum Gold Medal by the International Society for Ecological Communications in 2007.  Dr. Kerfoot is credited for the creation of a new area of research, “Resurrection Ecology” and he is an internationally known authority on paleoecology. Dr. Kerfoot is continuing as an emeritus research professor in our department.

Karyn Fay Portrait

The Biological Sciences department would like to acknowledge and celebrate the retirement of Medical Laboratory Science (MLS) Program Director, Karyn Fay. Karyn was such a memorable addition to the Biological Sciences Department and will never be forgotten. Before teaching at Michigan Tech, Karyn worked in many disciplines over the years and in a variety of places. In Virginia, she worked as a generalist. In Florida, she worked in a plasmapheresis clinic and then in a reference laboratory working mainly in steroid chemistry and fluorescent microscopy. In Arizona, she did microbiology projects related to immunology and virology. Before coming to Michigan Tech, she was the Hematology Supervisor at Keweenaw Memorial Medical Center in Laurium, MI for several years. Karyn began teaching in Michigan Tech’s MLS program in 2003. She later became the Program Director in 2013. Karyn officially retired in the spring of 2020. After retirement, she went on to help with the creation and development of the Michigan Tech COVID lab. Her efforts to help and support our students and the University as a whole were always tremendous. Throughout her years at Michigan Tech she educated and touched the lives of hundreds of students and left an indelible mark on the number of lives she came across. Her caring personality made her office a special place for students to talk and feel welcome. Karyn was instrumental in Michigan Tech’s MLS program obtaining accreditation from NAACLS in 2018 and she also received a university-wide teaching excellence award in 2016 for her outstanding teaching contributions. Karyn will always be remembered in our department for her expertise in laboratory medicine, positive attitude, and warm presence. She truly cared for her student’s success and will be dearly missed! We wish her a long and happy retirement.

Bob Stottlemeyer

Adjunct Professor Bob Stottlemyer Passed Away

Dr. John Robert (Bob) Stottlemyer, a faculty member at Michigan Tech from 1979-1990, died of natural causes on May 31, 2022, on a research expedition at a remote field site along the Agashashok River in northern Alaska.  He remained an adjunct professor with the Department of Biological Sciences until his death. Dr. Stottlemyer's three decades of research at the Agashashok River site was just a small part of his remarkable career studying environmental issues in northern landscapes and his incredibly full life of eight decades. He majored in forestry at Pennsylvania State University, with summer jobs fighting wildfires as a smoke jumper in the Sierra Nevada Mountains of California and working as an interpreter in national parks. He studied forest ecology for his Ph.D. at Duke University under the supervision of Professor Bill Ralston, focusing on forest soils and water quality. His Ph.D. research at the Fraser Experimental Forest in the Colorado Rockies was one of the first to combine the hydrology of mountain streams with water quality and nutrient budgets, an approach that persisted in his research over the next five decades, providing some of the best long-term records of forests and streams in the world. At Michigan Tech, he focused on hydrology, chemistry, and processes influencing water quality in remote watersheds from Calumet to Isle Royale National Park, Denali National Park, and Noatak National Preserve. Dr. Stottlemyer's loss leaves an emptiness in many lives, but each time he comes to mind, we all find ourselves smiling with so many grand memories of our unique colleague and friend.

Bill Campbell

Professor Bill (Dr. Wilbur H.) Campbell Passed Away

Emeritus Professor, Dr. Wilbur H. (Bill) Campbell passed away on January 30, 2022. Professor Campbell earned his Ph.D. in biochemistry from UW-Madison in 1972 and moved to the Keweenaw in 1985 to become a biochemistry professor at Michigan Tech. He was a brilliant scientist dedicated to his research. In 1993, Bill and his wife, Ellen decided to bring the discoveries of Bill’s academic research out into the world with new products for testing water quality. NECi, in Lake Linden, was one of the first biotech companies in Michigan. NECi’s products for nitrate testing won U.S. EPA method approval in 2017. These kits are made in Lake Linden and sold to customers worldwide. Dr. Campbell retired from Michigan Tech in 2003. He loved trees, birds, wildlife, cats, bears, and peace. The beauty of the area kept the Campbells here in the U.P., despite the winters.
