Teaching Experience

Supervision of Students and Postdocs

I supervised Piotr Pstra?gowski during his master’s degree, which he obtained in the Summer of 2014 from the University of Bonn.

I mentored the following Postdocs at the MPIM: Tobias Barthel, Rune Haugseng, Drew Heard, and Claudia Scheimbauer.
