My research is focused in the study of magnetised plasmas in a variety of solar system and astrophysical contexts. This research contributes to our understanding of solar system bodies, how they interact with their surroundings, and the basic plasma physics of these interactions. Most of my work focuses on the giant planets Jupiter, Saturn, Uranus and Neptune but I have also studied Venus. To carry out this research I use empirical modelling, in situ data analysis from spacecraft such as Cassini at Saturn, statistical studies, and theory/simulations.

I am happy to supervise PhD projects on topics in space and planetary physics covering giant planet systems (Saturn, Jupiter, Uranus, Neptune, and their moons/rings), and also astrophysical magnetospheres such as those around Brown dwarfs and exoplanets. PhD projects can either be focused on data analysis, using data from deep space missions such as Cassini-Huygens and Juno, or on computational modelling, or a combination. I have a particular interest in data science applications in planetary science and can offer projects with a strong element data mining, machine learning, and Bayesian analysis.

Space mission involvement:

• Jupiter Icy Moon Explorer (JUICE): Co-investigator J-MAG team.
• Cassini-Huygens mission to Saturn and Titan: member of the magnetometer and plasma spectrometer teams.
• Proba-2 Guest Investigator.
