Hello, I'm Audrey!

I am a fifth-year PhD student in Computer Science at UC Berkeley in the Sky Computing Lab advised by Ion Stoica and Natacha Crooks. My research focuses on transaction processing for database systems.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 systems. I am grateful to be supported by a NSF Graduate Research Fellowship, a Meta PhD Research Fellowship, and a Berkeley Chancellor's Fellowship.
