    Overview

    Biography

    Felix studied Computer Science with minors in Physics at the RWTH University of Aachen and graduated in 2012. In his PhD studies, which he concluded in 2016 in Aachen, he set out to apply the deep theory of sparse graphs to real-world network data. Felix completed a post-doc and Moore Data Fellowship at North Carolina State University, followed by a post-doc at Royal Holloway.

    In 2018 he joined ÌÇÐÄlogoÈë¿Ú as a lecturer and was promoted to senior lecturer in 2021. His main research goal remains to bring theoretical algorithms and data structures into practical applications.

    Research overview

    My research focuses on understanding and applying the structure of sparse networks—such as social, biological, and technical networks—through graph theory. One key aspect is the development of network algorithms based on these insights. My theoretical contributions include a novel characterization of graph classes with bounded expansion and techniques for efficient pre-processing, which help solve complex computational problems in practice. My practical contributions include an algorithm to index meta-genomes and a route-planning algorithm for robots.
