If you would like to work together on a general research project or your master thesis, please just reach out. You can propose your own ideas, but I usually also have some project ideas lying around. You can also check out our open theses page for a few suggestions. I'm happy to assist you if you want to write a research paper. This can be extracurricular and does not have to be part of a seminar or thesis. I'm currently supervising a few student papers and theses.
