# About Me

I am the Kollár research assistant professor at the University of Utah since August 2022. My post-doctoral mentor is Christopher Hacon. I did my Phd at école polytechnique fédérale de Lausanne (Sep 2017- Aug 2021) and I was a member at the institute for advanced study Sep 2021 -July 2022. I hold a grant from SNF that will finance my research 2022-2023 and 2024-2025. I'm co-organising the University of Utah Algebraic Geometry seminar since September 2023.
