I work at the chair of Prof. Holger Hermanns since June 2019. My PhD project revolves around the domain of space and satellites. 🚀 My work started with cost-optimal, energy-aware task scheduling for nanosatellites and has since shifted a bit towards efficient routing algorithms in large mega-constellations as well as other space-related topics. This fits well with one of the chair’s Advanced Courses, namely “Space Informatics”, of which I am the teaching assistant. I am currently the main developer of the LEOpowver project and am part of the team working on the MISSION project.

I received my B.Sc. in computer science in February 2018 and my M.Sc. in March 2020. My theses were on “A Modest Approach to Satellite Operation” and “Cache Persistence Analysis: Finally Exact”, respectively.
