My principal research interest is the study of planetary atmospheres. In particular, I investigate solar and auroral particle energy deposition in atmospheres of bodies throughout the solar system, using sophisticated kinetic and fluid models. Through close collaborations with instrument teams of major space missions (e.g., Cassini, Venus Express, Rosetta) I have used these models as binding elements between datasets from different instruments and thus optimized the scientific output from such measurements. I have focused so far on Venus, Earth, Mars, Jupiter and its magnetised moon Ganymede, Saturn and its largest moon Titan, comets, and gas-giant exoplanets.
