Biography

Professor Kong Lingkai is an Assistant Professor jointly appointed by the School of Computing and Data Science (host department) and the School of Public Health at the LKS Faculty of Medicine, The University of Hong Kong (HKU). Prior to joining HKU, he was a Postdoctoral Fellow at the Harvard John A. Paulson School of Engineering and Applied Sciences. He received his Ph.D. in Computational Science and Engineering from the Georgia Institute of Technology in the U.S.

His research focuses on building generative AI agents that can understand complex environments, reason effectively, and support decision-making in high-impact domains. He also works closely with public-sector partners in health and environmental sustainability to translate algorithmic innovations into real-world impact. His work has been published in leading AI and machine learning venues, including ICML, NeurIPS, and ICLR, and he has delivered tutorials at major data science conferences such as KDD. He is also a recipient of the Otto & Jenny Krauss Fellowship.
