Bio
I am PI of the Lise Meitner Programme M3184 of the Austrian Science Fund (FWF) at the University of Vienna with Michael Eichmair as coPI.
I obtained my doctoral degree at the University of Freiburg in 2020 under the supervision of Guofang Wang.
During my doctorate, I spent time at University College London as a visiting research student of Felix Schulze.
I won the FerdinandvonLindemannPreis for the best doctoral thesis and the Alumni Prize for the best master thesis of the
Mathematical Institute of the University of Freiburg.
