Han Liu is a Ph.D. student in computer science at the University of Chicago. He is a member of the Chicago Human+AI Lab (CHAI Lab), led by Prof. Chenhao Tan. His current research focus is on human–AI collaboration. It spans across explainability, AI alignment, and machine teaching.

He likes to think about the relationship between humans and machines, how they interact, and how they can collaborate. He is chasing a reality where humans can make the best use of automation when facing the greatest challenges in the world.

He earned his Bachelor's degree in mathematics, computer science, and linguistics at Washington University in St. Louis, where he developed his broad interests in artificial intelligence and natural language processing. He also spent a year at the University of Colorado Boulder as a Ph.D. student, before moving to Chicago.
