My research interests lie in the trophic ecology and energy dynamics of fish within aquatic ecosystems. Specifically, I am interested in the interactions of middle and lower trophic level species (i.e.  Freshwater Drum and White Perch) which contribute a significant proportion of biomass to ecosystems but are often overlooked in the literature as they do not garner much public interest since they are not considered “nuisance” or “sports” fish.


My Master’s thesis focuses on quantifying the energy dynamics of three common Lake Erie fish (Freshwater Drum, Walleye, and White Perch) using stable isotope analysis to inform us on the trophic position and diet of each species, and PCB’s to tell us the quantity of energy an individual has consumed throughout it’s life. This goal then is to begin creating a clearer picture of the Lake Erie ecosystem by beginning to understand how these species store and use the energy sources within the lake.
