Research Interests

I study the ecology, evolution, and conservation of aquatic ecosystems. Work in my group mixes field studies with large-scale spatial analyses and data syntheses. Focusing on fish and invertebrates, we try to understand the interface between animals and ecosystems in the context of human activities--what happens to rivers and lakes when their animal diversity is reduced, and what happens to animals when the temperature, chemistry, and physical structure of their ecosystem is altered. We have a special interest in the Great Lakes of North America and Africa, where we study how climate change, fisheries, and land use affect these enormous lakes. We also focus on migratory fish, and how landscape planning can restore migrations to their former glory. Our overall goal is to use insights from ecological research to inform ecosystem management and species conservation.
