  • Theoretical astroparticle and heliophysics
  • Loop quantum gravity
My main research focus is on general relativistic, semi-classical, and quantum gravitational models for black holes and their coupling to, and interaction with, fermionic and bosonic fields. Furthermore, I construct radiation emission models for blazars and magnetohydrodynamical models of the heliosphere and its vicinity. I also work on various research questions in quantum (field) theory in curved spacetimes.
