Scientific interests:

Turbulence related phenomena based on the so called Kraichnan model (and it's generalizations), which can be considered as a drastically simplified model of turbulence. Currently I am investigating stratified turbulence in the atmospheric boundary layer. I'm also dabbling with Lie symmetries, nonequilibrium field theory, conformal field theory and geometry of Lie groups.
