LEONG Tze Yun is a Professor of Practice of Computer Science at the School of Computing, National University of Singapore (NUS). She directs the Medical Computing Laboratory at the School. She is also the Director of the NUS Artificial Intelligence Laboratory (NUSAiL). Tze Yun received her SB, SM, and PhD degrees in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology (MIT), USA. Her research interests include responsible and decision-theoretic AI, neurocognitive modelling and causal reasoning, transfer and reinforcement learning, human-aware and adaptive computing, artificial general intelligence, and biomedical and health informatics. She has published and served on editorial boards and programme committees of leading international journals and conferences in AI and biomedical informatics. She is currently a Guest Editor of the Artificial Intelligence in Medicine series for the New England Journal of Medicine. She is an elected Fellow of the American College of Medical Informatics (ACMI) and a founding Fellow of the International Academy of Health Sciences Informatics (IAHSI). With both academic background and business experience, Tze Yun regularly contributes to panels and committees on education, research and development, and ethics and governance strategies and policies in Computer Science, Artificial Intelligence and Health Informatics in Singapore and abroad. She is currently serving in AI advisory roles for the Urban Redevelopment Authority (URA) in Singapore, the Advisory Council on AI in Uzbekistan, the AI in Health Ethics and Governance guidance initiatives of the World Health Organization (WHO), and the AI Governance Alliance of the World Economic Forum (WEF).
