In my research, I investigate the plasma physics of the solar wind and the solar corona. A plasma is a gas in which the ions and electrons are separated from each other and do not form neutral atoms like in a regular gas. The solar wind is a tenuous magnetised plasma. The moving charged plasma particles modify and react to electric and magnetic fields. This leads to a behaviour that is very different from the behaviour of neutral gases like the air. My work combines analytical theory, numerical simulations, and spacecraft observations to understand the fundamental physics behind the behaviour of plasma in space. I am especially interested in wave-particle interactions, kinetic waves and instabilities, turbulence, plasma heating, and shock waves.
