I joined the Massachusetts Cooperative Fish and Wildlife Research Unit in January 2012, where I serve as Assistant Unit Leader of Fisheries and Research Assistant Professor in the Department of Environmental Conservation at the University of Massachusetts-Amherst. I did postdoctoral research at the USEPA from 2004-2009, and was Assistant Professor at Kutztown University from 2009-2011.

Research Interests

My research broadly revolves around characterizing anthropogenic impacts on aquatic ecosystems and identifying conservation strategies for effectively protecting and restoring watersheds. The growing human population continues to constrain biotic assemblages in a variety of ways, and understanding the mechanisms by which urbanization and its associated stressors result in degraded fish assemblages is an overarching challenge of my research program. I am interested in examining effects of altered hydrology, temperature, habitat, water quality, and food resources on stream fishes; quantifying sublethal (e.g., behavior, physiology) responses of fishes to urbanization; and assessing potential for management (e.g., forested riparian buffers, green infrastructure, dam removal) to restore fish assemblages.

Teaching Interests

At the University of Massachusetts Amherst, I teach Research Concepts for first-year graduate students and Aquatic Ecology for advanced undergraduate and graduate students. In the past, I have taught graduate classes in Stream Ecology and Watershed Theory & Management, and undergraduate classes in the areas of Ecology, Conservation Biology, and Environmental Science.
