Yijun Liu 刘奕君 she/her

Hi there :) I'm a second-year Ph.D. student at the Siebel School of Computing and Data Science at the University of Illinois Urbana-Champaign, gratefully advised by Tal August. I am broadly intrigued by human-AI collaborative technologies that draw inspiration from human-human interaction strategies and emphasize human-in-the-loop collaboration.

I hold a B.S. in Computer Science and a B.S. in Quantitative Sciences in Sociology from Emory University.
