My research is focused in two areas: (1) developing new methods for studying fish population dynamics, particularly abundance and mortality; and (2) ecology and restoration of anadromous fishes (species that live in the ocean but spawn in coastal rivers). Methods for studying population dynamics include use of tagging and telemetry to estimate mortality rates and use of hydroacoustics to estimate abundance and site occupancy. Research on anadromous fishes has focused on abundance, migratory behavior, spawning ecology and effects of dams.
