Professor of Physics
My work specialises on the study of atmospheres around planets and other bodies (moons) in our solar system. I investigate their global characteristics and variability, including atmospheric waves and travelling perturbations.
Through a combination of numerical simulations and analysis of data from spacecraft such as Cassini/Huygens, Venus Express, ExoMars and in the future JUICE, I work to understand how the atmospheres interact with the solar wind and space environment.
More fundamentally, I study the highly non-linear and complex physical processes dominating in atmosphere and space environments under different external boundary conditions, including distance from the Sun, size and mass of the planet or moon, basic composition and magnetic and plasma environment.
I am Co-PI of the Radio and Plasma Wave Instrument onboard ESA's JUICE mission which is due for launch to Jupiter and its Galilean moons in 2023.
