I develop NuRadioOpt — a pipeline that makes full neutrino detectors in ice differentiable end-to-end, instead of optimizing isolated components independently. I also help maintain NuRadioReco/MC, teach statistical methods, and look after a small GPU server.
Personal projects
Projects and contributions outside my core research work.
Contributions to nixpkgs
Packaging, small fixes, and CI improvements for packages I use and maintain in NixOS/nixpkgs.
