About

I did my PhD in the Computing group (COMP) at the Department of Computer Science (IDI) at the Norwegian University of Science and Technology (NTNU), supervised by Magnus Lie Hetland. Previously I did a B.Sc. and M.Sc. in Computer Science at NTNU.

My research interests are in computation social choice, mainly focusing on fair allocation of indivisible goods.
