Hello hello! I'm a final-year (😅) PhD student at the University of Pennsylvania, advised by Andrew Head and Lyle Ungar. I study human-AI interaction, with a recent interest in human-centered NLP. My work is generously supported by the NSF GRFP Graduate Research Fellowship. Previously, I attended Carnegie Mellon University where I studied information systems and computer science.

I'm on the job market, looking for research scientist and applied scientist positions! If you (or anyone you know) might find my work of interest, please reach out ☺️

I'm interested in human-AI collaboration for knowledge extension: how AI can help people develop new knowledge that builds on what already exists (think: a mathematical conjecture, a scientific hypothesis, or a legal argument). AI is remarkably good at retrieving and reasoning over existing knowledge, but extending it is harder, and it helps to involve people. I build structured representations of existing knowledge that people and models can explore and reason over, and I develop and evaluate human-AI systems for deeply understanding and extending knowledge. See the current articulation of my research agenda here.

During internships at MSR Cambridge (Summer 2026) and Ai2 (Summer 2025), I studied how to optimize AI agents that shape what knowledge people incidentally learn, and how to develop paradigms for human-AI co-creation of research ideas, respectively.
