I am a post-doctoral researcher at the Institute of Theoretical Astrophysics at the University of Oslo, specialising in magnetised cosmological perturbation theory and the impact of primordial magnetic fields on the CMB, on cosmological backreaction and the averaging problem in cosmology, and on inhomogeneous cosmologies.
