Trophic/Food Web Ecology
Chemical tracers (stable isotopes and fatty acids)
Fish movement and habitat use

Research Interests:

My research focuses on understanding the mechanisms that drive the structure and function of trophic interactions and food webs, which I call trophic ecology.  I use a combination of chemical tracers (stable isotopes, fatty acids and mercury) and acoustic and satellite tag technology to quantify habitat use, diet and movement of fish and marine mammals from the Great Lakes to the Arctic marine environment.
