About Me
Hello! I am a final-year PhD candidate in Computer and Information Science at the University of Pennsylvania, advised by Prof. Chris-Callison Burch. My research focuses on evaluations of LLM’s capabilities for multilingual knowledge, with two overarching themes. On natural language processing (NLP), I study what multilingual knowledge is encoded into LLMs, building benchmarks and efficient techniques. On computational social science (CSS), I study how LLM’s knowledge can be used to understand contemporary society, with a focus on cross-cultural and cross-lingual concerns. Recently, I’ve been interested in studying how LLMs handle retrieved information from documents with diverse languages, sources, and perspectives.
I received BA and MS degrees in Computer Science from Columbia University, where I also minored in Linguistics and Economics. At Columbia I was advised by Profs. Julia Hirschberg and Kathleen McKeown. I have also pursued several research internships in industry at Microsoft, Amazon, and Google. I am active in the broader CS community through mentorship, teaching assistant roles, and conference reviewing. Feel free to get in touch at the links above.
