About Me

I am a PhD student in Computer Science (Machine Learning) at the University of Fribourg in Switzerland. I work with Professor Bastian Rieck in the AIDOS Lab and I am a member of the ELLIS PhD Program. My research lies at the intersection of machine learning and mathematics, with a particular interest in topology, geometry, and their applications to molecular systems and the natural sciences. I’m always happy to chat about research, potential collaborations, or other topics — feel free to get in touch!
