Xinyi Liu

I am a second-year PhD student in Computer Science at Northeastern University, advised by Prof. David A. Smith.

My research focuses on evaluating and aligning LLMs and AI agents, particularly how their reasoning, behavior, and interactions with humans remain consistent with human goals and agency. I am broadly interested in LLM/agent evaluation, alignment and AI safety, structured reasoning and information extraction, and human–AI interaction.

Previously, I conducted research at Microsoft Research in the Social Computing group and at Harvard Medical School in the HIDIVE Lab, where I was advised by Prof. Nils Gehlenborg. I received my M.S. from The University of Texas at Austin and my B.S. in Computer Science and Economics from the University of Maryland, College Park, where I worked with Prof. Zhicheng Liu and Prof. Hannah Bako.
