Since September 2020, I am a Senior Research Associate (senior assistant/Oberassistentin) at ETH Zürich. In Fall 2020, I will also be a remote member of the program Cohomology in Arithmetic held at CRM in Montréal.

My main research area is number theory, and principally connections with geometry and dynamics.

Recent & upcoming talks

Aug 14: CRM Members' Seminar
Oct 21: ETH, Geometry Seminar
Dec 4-7: CMS Winter Meeting Session on Probability in Number Theory
