Research Interests

I am interested in how life history, movement, and migration of organisms drive population dynamics and biotic interactions; how human activity may interact with these processes; and how such information may better inform conservation and restoration of aquatic systems. I pursue these interests using a variety of tools to investigate the population ecology and conservation of (mostly) freshwater and diadromous fishes; including studying how temporal and spatial variation in environmental conditions can influence migratory fish life cycles, and how migrations influence the productivity of tributary stream ecosystems.
