I studied Mathematics at the University of Ulm (Germany) from 2009 to 2013. Afterwards I was a PhDstudent of Dieter Rautenbach in Ulm until 2015. From 2015 to 2017 I was a Research Fellow at the University of Birmingham. Since August 2017, I have been supported by a DFG Research Fellowship.
My research focuses mainly on Algorithmic and Structural Graph Theory and Probabilistic Combinatorics.
