PhD candidate · astroparticle physics · differentiable detector optimization
In my PhD studies, I contribute to NuRadioOpt. Specifically, a pipeline that makes full neutrino detectors in ice differentiable end-to-end, instead of optimizing isolated components independently. Beyond physics, I'm interested in open-source software, computing, and exploring how technology can be put to practical use.
