Human.

MS student at CMU Language Technologies Institute, graduating December 2026. I'm obsessed with making AI agents that actually work on the open web — and quietly plotting my own startup on the side.

Before CMU: RLVR optimization at MSRA, multimodal ML at ByteDance, and grounding research at OSU NLP Group.
