Willy Quach

Email: willy dot quach at cispa dot de

I am a tenure-track faculty at CISPA Helmholtz Center for Information Security. Previously, I was a Postdoctoral Fellow at the Weizmann Institute of Science, hosted by Zvika Brakerski. I obtained my Ph.D. at Northeastern University, where I was advised by Daniel Wichs.

I'm broadly interested in the theory and foundations of cryptography.

I have open PhD and Postdoc positions. Feel free to reach out if you are interested!
