PhD Students
At the moment we have no funding for PhD positions, and we are not taking new PhD students.
Postdoctoral Researchers
We are happy to support applications with external fellowships (Humboldt, Marie Skłodowska-Curie, DFG individual grants) to be hosted in our group. Feel free to contact us early to discuss a joint application.
