My main area of interest is ices in the solar system.
This spans from atmosphere-surface interactions on Mars to plumes and surfaces of icy satellites of giant planets and comets.
- Laboratory investigations of planetary icy analogs and surface-atmosphere interactions on Mars;
- Understand the physics behind the plumes and jets in ocean worlds;
- Monitoring seasonally active areas on Mars and modelling of relevant processes;
- Citizen science project Planet Four.
