Interests

Since November 01st 2018 I am research associate of Communications - Systems - Applications Center of Excellence at the TH Lübeck - University of Applied Sciences. For my master thesis, I worked in the field of resource allocation in downlink broadcasts in industry 4.0 environments. In this regard, I developed a latency-based scheduling-algorithm. I'm interested in distributed systems, signal processing and algorithm research.
