We aim to better understand the flow of plasmas and properties of planetary bodies in our solar system and beyond.
For that matter we combine analytical models, numerical simulations and observations from spacecraft and telescopes.
Key Research Areas:
- Solar System Bodies and their Plasma Environments
- Searching and Characterising Extraterrestrial Subsurface Oceans (within ERC-Advanced Grant EXO-OCEANS)
- Turbulence in Space Plasmas
- Exoplanets
- Planetary Atmospheres
Key Methods:
- Numerical Simulations
- Analytical Theory
- Telescope Observations
- Spacecraft Observations
- Time Series Analysis
