Research Interests

Artificial intelligence and machine learning influence every aspect of our modern world. In my opinion, the responsibility of research is to improve the application of these approaches by developing collaborative, privacy-preserving algorithms. These algorithms can be further improved by using already existing expert knowledge which is especially difficult to aquire in the medical sector.

Therefore, my main research interests manifest in

Informed Machine Learning
Federated Learning
Health Information Systems
