About me
I am currently a PhD student at TU Berlin under the supervision of Prof. Dr. Martin Skutella. My research interest lies in Combinatorial Optimization, more specifically in network flow problems and approximation algorithms.
Prior to that, I have received my M.Sc. in Mathematics (minor in Theoretical Computer Science) at EPFL in Switzerland. My master thesis about algorithms for diversity maximization was advised by Prof. Dr. Friedrich Eisenbrand.
