My current research interest includes atmospheric circulation and climate dynamics of exoplanets, from gaseous giants to terrestrial planets, with orbital periods from a few hours to tens of year. I am also investigating dynamical processes and cloud formation in atmospheres of brown dwarfs (failed stars, and more massive hydrogen-helium fluid counterparts of giant planets), and the links to unsolved observational puzzles.
