Xufei Liu

I am a fifth-year PhD candidate in Operations Management at The Wharton School, University of Pennsylvania, advised by Gad Allon and Ken Moon.

My research studies the human side of AI and monitoring technology in operations: what tools such as LLM assistants actually do to the people who use them, and when organizations should intervene to keep technology-assisted work productive and sustainable. I work with physiological and behavioral sensor data collected in lab and field experiments — from clinicians and students writing with LLM drafts, to U.S. Air Force aviators on training flights, to learners on a large language-learning platform. Currently, I have worked on projects that use experiments, decision-focused machine learning, and reinforcement learning.

Before Wharton, I received a B.S. in Industrial and Systems Engineering from the Georgia Institute of Technology (Honors Program).
