I studied Applied Computer Science with a minor in Physics at the Ruprecht-Karls-University Heidelberg and received my Master of Science in March 2018. My master thesis investigated the concept of anti-community structures in networks and proposed multiple algorithms for efficient anti-community detection. Since April 2018 I am working as a researcher and PhD student at the Institute of Computer Science in the Database Systems Research group of Prof. Dr. Michael Gertz.
