My current main field of interest is high-energy astrophysics including phenomena such as gamma-ray bursts, supernovae and soft gamma-repeaters and physical processes such as colissionless and radiation mediated shocks, shock breakouts, particle acceleration, relativistic hydrodynamics and radiative transfer. In the past I also studied topics in complex systems and nonlinear dynamics. Below you can find a description of some of the topics that I studied over the years.
