Dr. Kunpeng Liu is an assistant professor in the Department of Computer Science at Portland State University. He received his Ph.D. degree from the Department of Computer Science, University of Central Florida, Orlando, FL in 2022. He received both an M.E. degree and a B.E. degree from the Department of Automation, University of Science and Technology of China (USTC), Hefei.

He has broad interests in data-centric AI (DCAI), large language models (LLMs), and reinforcement learning (RL), especially in efficient fine-tuning and effective reasoning of LLMs, with application to big data problems, including traceable and explainable feature engineering, reasoning on recommender systems, and spatiotemporal user behavior analysis. He has published more than 60 papers in refereed journals and conference proceedings. He serves as AC/SPC/PC for various conferences, including ICML, ICLR, NeurIPS, KDD, ICDM, SDM, WWW, CIKM, IJCAI, and AAAI. He has co-organized one tutorial and five workshops on DCAI. He is the Financial Chair of IEEE ICKG 2024 and Registration Co-Chair of IEEE BigData 2024. He is a recipient of the Best Paper Runner-up Award from IEEE ICDM 2021. He is a recipient of the NSF CRII Award.
