## About

Hello, I'm Daniel Siemssen. I'm currently doing research on deep learning and uncertainty quantifications methods applied to computer vision and sensor fusion problems for autonomous driving. Previously, my research focused on mathematical physics and in particular mathematical aspects of quantum field theory in curved spacetimes.
