Stephen Xie

I am a researcher at UC Berkeley and BAIR Natural Language Processing (NLP) Group , where I'm fortunate to be advised by Jiayi Pan and Alane Suhr. I'm interested in understanding and maximizing the capabilities of language models. My research primarily focuses on efficiently training robust reasoning models through RL. Previously, I worked on mechanistically interpretability and LLM steering at CTGT (YC F24). I am double majoring in Electrical Engineering and Computer Sciences (EECS) and Business Administration under the M.E.T. program.
