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.
• 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)
