The purpose of our work is to understand the fate and effects of chemicals in the environment in order to guide sound public policy decisions—a mission that is motivated by a respect for nature and desire to conserve biodiversity on Earth. We do research not only on the causes, but also the solutions, to aquatic pollution. By conducting large-scale, interdisciplinary field studies, we answer questions on a broad range of contemporary problems, including mercury contamination of food webs, nutrient pollution and harmful algal blooms, and the ecological impacts of extracting and transporting unconventional oil.


My goal as a teacher is to ensure students not only learn the fundamental content of academic courses, but also develop important life-long skills (specifically, critical thinking, problem-solving, and communication) to prepare students for their future careers. Further, I seek to inspire students by sharing my own passion for biology and environmental issues, and empower students by fostering a collaborative, interactive environment in the classroom.

Teaching Interests: Ecology, Limnology, Ecotoxicology, Global Water Issues, Science Communication
