I examine patterns and test hypotheses regarding the causes and consequences of the distribution, abundance, and movement of aquatic organisms. This includes determining the distribution and movement of animals (e.g., alewife, striped bass, blue catfish, crayfish and Pacific salmon) using telemetry and then relating those movements to environmental factors that cause them to stay or move. I also examine the relationships between ecological drivers and fishes including environmental heterogeneity, abiotic gradients, and anthropogenic activities.
