Currently I am studying the interplay between radiative balance and atmospheric dynamics on giant planets such as Jupiter, having previously studied terrestrial planets including Venus. Jupiter and Venus both have atmospheres deeper than Earth’s, which allows room for potentially more complex circulations. For my doctoral thesis I worked on plasma turbulence in fusion devices, and I have a general interest in the relationship between small and large scales.
