I have received my PhD at the Free University Berlin in April 2017 under the supervision of Holger Reich. I was a Postdoc at Purdue University under the mentorship of Jeremy Miller. I am currently a Postdoc at Copenhagen University as part of the Centre of Geometry and Topology and my mentor is Nathalie Wahl.
