Internal Research Fellow (Postdoc) in the Advanced Concepts Team at ESA working on fast, efficient, interpretable and robust machine learning models for spacecraft.

I completed my PhD at the University of Bonn in the Machine Learning and Artificial Intelligence Lab under supervision of Christian Bauckhage and Stefan Wrobel. Meanwhile I was also working at Fraunhofer IAIS and part of the LAMARR institute.

My research lies at the intersection of machine learning, combinatorial optimization, and hardware-aware computing. I develop algorithms tailored to their underlying hardware, ranging from quantum computers to efficient logic-based neural networks. My work combines practical algorithm design with rigorous theoretical analysis.
