About Me

I am a PhD candidate at the CISPA Helmholtz Center for Information Security, and advised by Franziska Boenisch and Adam Dziedzic. My research focuses on privacy and security for machine learning.

Before joining CISPA, I completed an MSc in Data Science at ETH Zurich, where I worked with Florian Tramèr. I previously earned a BSc in Engineering of Computing Systems from Politecnico di Milano.
