I am a tenure-track assistant professor in the Algebra, Geometry, and Number Theory group in the Mathematical Institute of Leiden University.

Before this, I held postdoc positions in Leibniz University Hannover, Max Planck Institute for Mathematics in Bonn, and Max Planck Institute for Mathematics in the Sciences in Leipzig. I completed my PhD in Mathematics at Humboldt University of Berlin with a short stay at University of Amsterdam.
