My research interest is machine learning with differentiable algorithms. For example, I have made a general framework for making algorithms differentiable, and have also focussed on differentiable sorting and differentiable rendering. While making algorithms differentiable by propagating distributions through them is a lot of fun, I also like propagating distributions through neural networks, which improves uncertainty estimation, robustness, and fairness.

I work in the Visual Computing Group (Prof. Oliver Deussen) at the University of Konstanz and in collaborations with Christian Borgelt, Hilde Kuehne, Mikhail Yurochkin, among others.

In the past, I was working, i.a., at TAU, DESY, PSI, and CERN.
