Dr. Jennifer DeBruyn, PhD, is an Associate Professor in the Department of Biosystems Engineering & Soil Science. She is a microbial ecologist, studying how microbes interact with each other and their environments to perform critical functions for their ecosystems.
Having grown up on a field research station in northwest Ontario, environmental science has always been her primary interest. As a PhD student, she worked on pollutant remediation in sediments. As a faculty member in BESS, her main research areas are decomposition and biodegradation in both agricultural and natural ecosystems. One of her focus areas is the biodegradation of agricultural plastics, where she and her students investigate impacts of biodegradable plastics on soil health and study microbes that can break down plastics. They are answering questions that are critical to policy questions related to use of biodegradable plastics in agriculture.
