Audrey Cheng

CS PhD Student, UC Berkeley

Hello!

I'm Audrey Cheng, a second-year PhD student in Computer Science at UC Berkeley advised by Professors Ion Stoica and Natacha Crooks. I'm broadly interested in databases and distributed systems. I'm affiliated with the RISELab, and I'm supported by a Berkeley Chancellor's Fellowship.


Previously, I graduated with a BSE in Operations Research and Financial Engineering from Princeton University, where I was fortunate to work with Wyatt Lloyd and Kai Li. I have interned on the Themis team at Facebook, which focuses on providing stronger consistency and isolation guarantees for large-scale system.
