Hello
My name is Michele Orrù (@mmaker). I am a postdoctoral researcher at UC Berkeley, under the supervision of Alessandro Chiesa. Before, I was a PhD student at École Normale Supérieure, under the supervision of Georg Fuchsbauer. I completed my graduate work in math at the University of Trento.
I am interested in zero-knowledge proofs, and more broadly in cryptography. My research includes building authentication mechanisms that preserve user privacy and anonymity. In the past, I have contributed to Python, Debian, and Tor.
