I am a Senior Research Associate (Oberassistentin) at ETH Zürich. My research is in number theory, and its connections with geometry and dynamics.
Starting February 1, 2022, I will be assistant professor (SNSF PRIMA Professor) at the University of Zurich.


Spring 2022: Topics in number theory: L-functions and modular forms (UZH)
Spring 2021: Spectral theory of hyperbolic surfaces (ETH)
