Welcome to my personal homepage! I am an Associate Professor in Space Plasma Physics at the Mullard Space Science Laboratory. I study the physics of plasmas in the solar system and beyond, such as the solar wind, the solar corona, accretion discs around black holes, and the medium between galaxies, with theoretical models, numerical simulations, and spacecraft observations. This research is of great importance for our understanding 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 an understanding of space weather 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.
