**I am interested
in mathematical physics and nonlinear**
**phenomena.
In particular, I am interested in semiconductor laser**
**theory, nonlinear
and fiber optics, surface water waves, acoustic**
**waves and gas lasers.
Although these topics are seemingly**
**disconnected and
have quite different physical nature, they all can be**
**viewed as complex
systems composed out of interacting particles or**
**waves. There is a
general theoretical framework for their description,**
**called weak turbulence
theory. I am trying to both**
**further develop weak
turbulence theory and to use these developments**
**to study such complex
systems.**
