I'm a postdoc in astrophysics at the Institute for Theoretical Astrophysics, University of Oslo.

I'm interested in the early Universe, how galaxies were formed, and how they evolved. In particular, I'm interested in how the light that the stars and gas emitted som ten billion years ago traveled through interstellar and intergalactic space and down to our telescopes, forming beautiful images.

More formally, my research involves radiative transfer, Lyman α radiation, damped Lyman α absorbers, gamma-ray bursts, galaxy formation, Reionization, and, um, dust.

Although my research is mostly numerical, i.e. it takes place inside a computer (and my head), once in a while I have been lucky enough to have the opportunity to go observing, among other things the afterglows of gamma-ray bursts. Below are some nice pictures of beautiful celestial objects taken with various telescopes, when the weather conditions did not allow me to do scientific observations.
