My research background is in passive acoustics and signal processing applied to understand the timing and location of reproductive activity by sound producing fishes. These methods are used to understand the reproductive ecology of fishes and the acoustic ecology of a diverse range of habitats and how the use of these habitats varies naturally and in response to human induced changes on broad time scales. I am also interested in developing new instrumentation for understanding fish spawning and in combining existing technologies for a comprehensive characterization of fish spawning aggregations, spawning ecology, and factors which affect the downstream abundance and distribution of newly recruited fishes.
