Fermi Ma
I am a Simons-Berkeley Postdoctoral Fellow hosted by Prof. Umesh Vazirani. I earned my Ph.D. at Princeton in 2021, where I was advised by Prof. Mark Zhandry. Before that, I received my B.S. in mathematics from MIT.
My research focuses on the interplay between cryptography and quantum information/computation.
Spring 2023: I’m co-teaching CS:294-236. Cryptography in a Quantum World with Umesh Vazirani.
