🎓 Academic Background

Jun 2021 M.Sc. in Scientific Computing at TUB
Feb 2018 B.Sc. in Engineering Science at TUB

🔬 Research

My research interests lie at the intersection of optimization and machine learning. In particular, I am interested in online optimization, federated learning and optimization on riemannian manifolds.
