Nicholas Johnson, Ph.D.

Biography

I study fisheries with a focus on invasive species control and native species restoration in the Great Lakes through enhanced understanding of their sensory ecology and population demographics.  I earned my B.S. degree from the University of Wisconsin – Stevens Point, and M.S. and Ph.D. degrees from Michigan State University. I became a research ecologist with USGS, Great Lakes Science Center, Hammond Bay Biological Station in 2009, serve in adjunct appointments at several universities in Michigan, and am an assoicate editor of the Journal of Great Lakes Research.  My research is mostly in collaboration with the Great Lakes Fishery Commission where I am a member of the Sea Lamprey Trapping Task Force and Barrier Task Force.
