My research is primarily focused on underwater acoustics, 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 to study natural phenomena, such as oceanic variability at different scales. In particular, I am interested in identifying the oceanic features that control acoustic wavefield structure and stability and in understanding the conditions under which these features should be described deterministically or stochastically. I am also interested in advancing long-range acoustic communication methods.
