Acoustic-gravity waves (AGWs), which encompass gravity waves and infrasound, couple wave processes in the ocean and solid Earth with those in the middle and upper atmosphere, play an important role in the momentum transfer in the atmosphere, and provide a key to understanding ionospheric manifestations of tsunamis, earthquakes, and other natural and anthropogenic phenomena occurring near the ground level. Theory and mathematical modeling of AGW generation, propagation, dissipation, and coupling in inhomogeneous and non-stationary media are areas of active research. Current research interests include distributed fiber-optic sensing of acoustic, gravity and acoustic-gravity waves in the ocean and atmosphere, understanding the ambient wave field in the atmosphere; modeling of generation of AGWs and their propagation in the ocean and atmosphere; modeling of low-frequency ambient underwater sound; and acoustic noise interferometry for passive remote sensing of the environment.
