Research Interests

I am interested in the use of underwater acoustics to study a variety of biological and physical oceanographic processes. Using underwater sound, we can non-invasively measure a variety of marine processes (zooplankton and fish distributions, submerged aquatic vegetation, turbulence and microstructure) with high temporal and spatial resolution.

My laboratory combines a variety of research methodologies to investigate these issues including: development of physics-based scattering models for different organisms/processes, validation of these models through scattering experiments conducted in laboratory tanks, collection of field-data in both estuarine and pelagic environments, and interpreting field survey data to better understand the oceanic environment.

Current research projects include: field surveys of Antarctic krill populations near the Antarctic peninsula, physical factors influencing the retention of krill in the nearshore environment, the distribution of zooplankton populations as they relate to foraging effort from predators, use of acoustics (including instrument development) to map and measure submerged aquatic vegetation in estuarine environments, scattering model development for gelatinous zooplankton, submerged aquatic vegetation, and temperature and salinity microstructure.
