I am an assistant professor in the EECS Department at UC Berkeley.
I am affiliated with the Theory, Cryptography, and Security research groups.
I am an author of libsnark, a C++ library for zkSNARKs, which are zero knowledge proofs that are very short and easy to verify.
I am a coinventor of Zerocash and cofounder of Zcash [ ], both of which rely on libsnark.
I am a cofounder of StarkWare Industries.
I am broadly interested in Theoretical Computer Science and Computer Security.
Specific interests include theoretical and applied cryptography, complexity theory, mechanism design, and others.

I joined UC Berkeley's faculty in the summer of 2015.
Prior to that, I spent one year as a postdoctoral researcher at ETH Zürich; my host was Prof. Thomas Holenstein.
I earned my Ph.D. in the Theory of Computation group in CSAIL at MIT; my doctoral thesis advisor was Prof. Silvio Micali.
I earned my M.Eng. in the same group; my master's thesis advisors were Prof. Eran Tromer and Prof. Ron Rivest.
I earned my S.B. in Mathematics and my S.B. in Computer Science at MIT; outside of classes and labs, I rowed for the heavyweight varsity crew team at MIT.
A list of my old coursework while at MIT can be found here.
Before coming to MIT, I lived in Varese, Italy, where I was born in 1987. While in Italy, I attended the European School of Varese from kindergarten through high school; this school is part of the system of European Schools, which awards students the European Baccalaureate.
I enjoy many outdoor sports, including biking, climbing, mountaineering, and running.
The best way to contact me is via the email at the top of this page.
My office is located in 683 Soda Hall.
