Fredrik Kahl

I am a professor at Chalmers University of Technology leading the Computer Vision Group. I am an applied mathematician interested in geometry, optimization, computer vision and machine learning, in particular, geometric deep learning.

I was previously a professor at the department of mathematics, Lund University (2006-2018) and before that, a post-doctoral fellow at the department of Computer Science, University of California San Diego (2005-2006) and at the Australian National University (2004-2005). I did my PhD at Lund University under the supervision of Profs. Anders Heyden and Gunnar Sparr (1997-2001).
