Erin joined the Raby Lab in September 2021 and is co-supervised by Dr. Jake Brownscombe (DFO) for her M.Sc. in the Environmental and Life Sciences graduate program at Trent University. The aim of her research is to develop laboratory-based bioenergetics estimates in adult walleye (Sander vitreus) to help lay the groundwork for field-based estimates of energy use. Her research focuses on calibrating accelerometer transmitters for metabolic rate in walleye to examine activity costs across size, sex, and temperature differences.

Erin completed her B.Sc. in Environmental Science with a concentration in Ecology, Biodiversity, and Conservation at Carleton University in 2021. Throughout her undergraduate degree, she has had many opportunities to engage in outreach activities, environmental enhancement projects, and field courses. In a field course at the University of Windsor, she investigated the trophic positions of fish species in the Detroit River using stable isotope analysis and assessed the distribution of common carp (Cyprinus carpio) using acoustic transmitter tags. At Laurentian University, she investigated how land-water linkages affect food web structures by conducting rapid littoral fish community assessments within recovering acid-damaged lakes. Erin completed her undergraduate thesis data collection at the University of Victoria where she investigated the effects of biological and anthropogenic noise on the physiology and behaviour of Chinook salmon (Oncorhynchus tshawytscha) and rainbow trout (Oncorhynchus mykiss) through analysis of cortisol in blood plasma.
