The main interests are related to the study of a wide range of physical processes in the boundary layers of the atmosphere and the ocean. In this case, the main research method physical modeling on experimental facilities. The main studies were devoted to:

1. Studying the processes of turbulent exchange between the atmosphere and the ocean under severe conditions (storms and hurricanes).
2. Investigations of the physics of small-scale multiphase processes (sprays, bubbles, foam) and their role in the interaction of the atmosphere and the ocean.
3. Study of the features of the processes of scattering of microwave radiation on a marine rough surface in order to develop remote sensing methods.
4. Investigation of turbulent flows in a stratified fluid in application to the problems of mixing the upper layer of the world ocean and its pollution in the coastal zone.
5. Laboratory modeling of a wide range of body and hydrodynamic and heat transfer processes in power plants, including nuclear power plants.
6. Development of new methods and means of aero- and hydrodynamic experiments based on visualization using advanced laser-optical technologies and high-speed filming.
