Primary 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.

Current Projects

• Impacts of surface water supply reservoirs on stream flow and biology in small Massachusetts watersheds

• Investigating impacts of lake drawdowns on fish and wildlife

• A heads up view of aquatic ecosystem sustainability: understanding the terrestrial landscape scale impacts of urbanization on aquatic biota

• Understanding the factors that influence outdoor residential water conservation: a case study in suburban Boston

• Stream macroinvertebrate and periphyton responses to watershed-scale stormwater management (with the US Environmental  Protection Agency)

• Effects of urbanization on stream insect drift (with Kutztown University)

• Fish recovery following experimental defaunation in urban and forested streams (with Kutztown University)
