Roman Feller

Since October 2023 I am a PhD student supervised by Michael Pinsker working in the ERC Synergy Grant POCOCOP at TU Wien. I obtained my master in mathematics from the University of Bonn where I wrote my thesis with Philipp Hieronymi.

My research interests lie in infinite domain constraint satisfaction problems (CSPs) and related questions in model theory and Ramsey theory.
