Pontus Giselsson

I am an Associate Professor at the Department of Automatic Control. My main research interests lie within optimization and its wide range of applications.

Open Positions

I have an open PhD position in the intersection of optimization, learning, and control with an emphasis on the former two. Application deadline is October 15.
