Welcome to my personal homepage! I am an Associate Professor in Space Plasma Physics at the Mullard Space Science Laboratory. I study the fundamental physics of plasmas in the solar system and beyond. These cosmic plasmas include the solar wind, the solar corona, accretion discs around black holes, the interstellar medium, and the medium between galaxies. I use theoretical plasma models, numerical simulations, and spacecraft observations to investigate the relevant plasma processes. This research is of great importance for our understanding of astrophysical systems across the Universe, since more than 99% of the baryonic matter in the Universe is in the plasma state. Moreover, my research is important for the comprehension of space weather, which poses a serious threat to humans and to our technology both in space and on the ground. I am working towards a physics-based understanding of space plasmas that enables successful and accurate predictions of this hazard. You can find more details about my research here or directly in my list of publications.
