Although I was officially born and raised in Minneapolis, I really grew up at our family cabin in northern Minnesota. There I could hike the trails, fish the lakes, dig in the dirt, and poke around in streams to my heart’s content. I parlayed that interest into a degree in limnology and fisheries management in 1994 from the University of Wisconsin–Stevens Point, where I decided to become a professor so I would never really have to leave college. I received a master’s degree in ecology from the University of North Texas in 1997 before going back home to obtain my Ph.D. in entomology from the University of Minnesota in 2002. My dissertation involved the biological diversity of aquatic insects, specifically the caddisflies, and how those populations were affected by natural and human disturbances. Basically, it meant that I got paid (albeit poorly) to go camping and explore the streams and rivers of the state for four years.
After graduate school, I taught at a liberal arts college in Virginia for a couple of years before coming to Hillsdale in 2005. I became the director of the College’s G.H. Gordon Biostation in 2008 and chair of the Biology Department in 2018. I’ve also served a couple of terms as president of the Michigan Entomological Society, which means hosting their annual research conference at our Biostation.
My teaching and research interests remain at the intersection of invertebrate biology and freshwater ecology. My students and I travel all over the northcentral US, sampling streams and relating the aquatic insect populations that we find to natural and anthropogenic conditions. We’ve been fortunate to sample some truly unique and generally inaccessible habitats, such as the remote Huron Mountains of the northern Upper Peninsula, the Black River Ranch of the northern Lower Peninsula, and Algonquin Provincial Park in Ontario. We have compiled the largest caddisfly collection in Michigan, with nearly 300,000 specimens collected over the last 10 years.
At the Biostation we study everything from spiders, to salamanders, to snapping turtles. Many of my students present their research at professional conferences, and a good number of them also publish their findings in peer-reviewed scientific journals, which is a rare and crowning achievement for an undergraduate.
My wife and I live in Hillsdale with our passive-aggressive English Shepherd. I spend my free time scuba diving, mountain biking, and exploring remote wilderness areas by foot and packraft.
Feel free to email me if you have any questions about the teaching and research happening at the Biostation or in the Biology Department in general. I am always happy to talk with prospective students and their parents.
