Hello, I'm Audrey!

I am a third-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. Most recently, I have built TAOBench, a new transactional benchmark that captures Meta's social network workload.

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.
