I'm a postdoc at the Helmut-Schmidt-University. My current research addresses the utilization of reinforcement learning for complex task architectures. I'm also investigating quantitative methods to enhance large behavioral data sets for personality psychology research.

I was co-author of the TensorForce reinforcement learning library. Currently, I'm working with two friends on RLgraph, a new, modular, backend-independent enterprise-ready reinforcement learning library.
