I am a Professor of Astrophysics and Deputy Head of the Physics Department at KTH. I am also a Wallenberg Scholar. Before starting at KTH I did my MSc at Lund University, a PhD at the University of Cambridge and a postdoc at Stockholm University.
My main research interests are supernovae and their remnants, gamma-ray bursts, and active galactic nuclei. My group is using multiwavelength observations to tackle unsolved problems regarding these phenomena, such as the explosion mechanism and properties of relativistic jets.
One of my favourite objects of study is the nearby Supernova 1987A. Here is a popular science introduction (in Swedish) to this research.
