About me

My field of research lies in high-energy astrophysics, and in particular the processes that occur around black holes. I obtained my PhD from Stockholm University, and have done post docs and research fellowships in Lund, at KTH and in Tokyo. I am now back in Stockholm where I split my time between the Departments of Astronomy and Physics.

In addition to research I have always enjoyed teaching and pedagogical development. Through funding from the university I have conducted several projects to improve the pedagogical environment, and together with Emma Wikberg at the Department of Physics I am running a long-term project aimed at improving the transition to university for first-year bachelor students.

Research

The overall purpose of my research is to increase our understanding of the physical processes occurring in accretion flows around black holes. This comprises both the accretion flow in X-ray binaries, as well as the immensely powerful jets of gamma-ray bursts. The extreme environment close to the black hole means that high-energy radiation is produced, and observations must therefore be made in the X-ray and gamma-ray bands.

Black holes are among the most exotic phenomena in our Universe. By their nature, they cannot be directly observed and must be studied through their interactions with their surroundings. One of the few ways to do this is to study the process of accretion. As matter falls into the black hole, some of the gravitational energy is converted into observable radiation, and some can also go into powering dramatic relativistic ejection of material via a jet. How this jet is produced is one of the major open questions in modern astrophysics and it likely depends on both the black hole spin as well as the nature and power of the accretion flow around it.

One thing I particulary enjoy is the international nature of the research community. I have collaborators across the world, such as the UK, Italy and Japan.
