I am currently a postdoc at the University of Bremen, in the team of
Sebastian Siebertz.
Before that, I was a postdoc at the University of Warsaw, funded by the ERC grant Lipa of
Mikołaj Bojańczyk.
A couple of years earlier, I was a PhD student at the University Paris Diderot under the supervision of
Arnaud Durand and Luc Segoufin.
