My research program is focused on aquatic ecology. I am interested in investigating aquatic community structure and function to help provide insight for designing monitoring strategies, understanding the causes and consequences of species loss, and contributing to conservation and management. My lab aims to understand existing aquatic communities, how they function, how they came to be, and how they will respond to future stressors. Our work harnesses traditional ecological data (e.g., water quality, habitat availability, assemblage diversity) from field, laboratory, and museum studies of freshwater systems to identify the ecological and environmental context relevant to aquatic community composition and function. We address questions about whether aquatic communities are constrained by anthropogenic activities and work to develop mitigation strategies for negative environmental impacts. My research speaks to current questions in ecology by addressing the ecological role of species at multiple life history stages, investigating the nature of species interactions and how they shape community structure (including invasion), and developing models to forecast how species distributions will be altered in changing environments.
