I am a PhD student working at Lund Observatory on planet formation with Anders Johansen as my supervisor.

PhD Thesis:

I am studying the formation processes of the building blocks of planets, planetesimals. How do you get from dust in protoplanetary disks to km-sized objects? I investigate, through numerical simulations, the formation of pebble-pile planetesimals through the collapse of self-gravitating clouds of pebble-sized particles in a protoplanetary disk. The current goal is to find the internal structure of comets and other planetesimals in the outer regions of the Solar system.
