I'm a University Researcher at the space physics group, University of Helsinki, Finland. My current research topics include terascale simulations of ion-kinetic plasma physics the Earth’s magnetosphere and bow shock, focusing on particle injection and acceleration in addition to foreshock physics. I am one of the main code developers for Vlasiator and am the author of the eVlasiator electron model, now leading our project in GPU acceleration. In the past I have been involved in research on the acceleration, propagation, and detection of Solar Energetic Particles. I’m most interested in researching new ways to investigate plasma physics phenomena through computational physics.
