Dr. Jan Bartsch

In November 2021, I completed my PhD under Prof. Alfio Borzi at the University of Würzburg.
I also completed my bachelor's and master's degree there.
Since 2021, I have been a research assistant working with Prof. Volkwein.

This postdoc position is supported by the German Research Foundation DFG project SFB 1432 (Project Title: Fluctuations and Nonlinearities in Classical and Quantum Matter beyond Equilibrium).
