Research Interests

Underwater acoustics, sound propagation physics, geoacoustic interactions, geoacoustic inverse problems, dispersion and scattering of sound waves in the ocean, acoustic signal processing

Research Statement

My research is primarily focused on ocean acoustics and acoustical oceanography, understanding the physics and principles of sound propagation in the ocean, scattering by internal waves and mesoscale variability, and interaction of sound with the seafloor.  I am interested in using acoustics for ocean remote sensing, to study natural phenomena, such as oceanic variability at different scales, and in identifying the oceanic features that control acoustic wavefield structure and stability. I am also interested in advancing long-range acoustic communication methods.
