I'm a 4th year PhD student in CS at Princeton University, advised by Danqi Chen, and affiliated with Princeton Language and Intelligence. Previously, I was an undergraduate at the University of Cambridge, where I was fortunate to work with Adrian Weller. During my PhD, I have also spent time interning at the Ai2.

My research interests revolve around building and understanding large language models, with a particular focus on their training data (QuRating, WebOrganizer, ProLong, Masking Rates). I have also worked on understanding why LMs are easy to adapt (via Kernel Behavior) and how we can interpret their internal workings (Transformer Programs, Edge Pruning).

I am also part of the team that built SWE-bench and SWE-agent.
