Xiaohui Liu

I am Xiaohui Liu (in Chinese, 刘晓慧), currently a Research Fellow in the Department of Information Systems and Analytics at the National University of Singapore, working with Provost’s Chair Professor Jungpil Hahn. Prior to this, I was a Research Fellow at the Institute of Operations Research and Analytics (IORA) at NUS.

I received my Ph.D. in May 2026 from the Department of Information Systems and Analytics, School of Computing, at NUS. My Ph.D. advisor is Provost’s Chair Professor Hock-Hai Teo. Before joining the Ph.D. program, I worked as a Research Assistant with Associate Professor Wei Ma in Transportation Engineering at The Hong Kong Polytechnic University. I received my Master’s degree from Beihang University and my Bachelor’s degree from Zhengzhou University. Please see my CV here.

My research examines how AI algorithms reshape human decision-making and how they can be redesigned to better support it. I study these questions in the context of digital platforms, including ride-sharing, FinTech, and recommender systems. Methodologically, I draw on my interdisciplinary training to combine large language models, causal machine learning, data mining, econometric analysis, and behavioral experiments.

I am on the job market for 2026-2027.
