Dr. Bui received his PhD in Computer Science in 2000, upon which he joined the UCLA faculty. He is now the Director of the Medical & Imaging Informatics (MII) group. His research includes informatics and data science for biomedical research and healthcare in areas related to distributed information architectures and mHealth; methodological development, application, and evaluation of artificial intelligence (AI) methods, including machine/reinforcement learning; and data visualization. His work bridges contemporary computational approaches with the opportunities arising from the breadth of biomedical observations and the electronic health record (EHR), tackling the associated translational challenges.

Dr. Bui has a long history of leading extramurally funded research, including from multiple different National Institutes of Health (NIH) institutes (NCI, NLM, NINDS, NIBIB, etc.). He was Co-Director for the NIH Big Data to Knowledge (BD2K) Centers Coordination Center; and Application Lead for the NSF-funded Expeditions in Computing Center for Domain-Specific Computing (CDSC), exploring cutting-edge hardware/software techniques for accelerating algorithms used in healthcare. He led the NIH-funded Los Angeles PRISMS Center, a U54 focused on mHealth informatics. He is now Director of UCLA’s Bridge2AI Coordination Center, a landmark NIH initiative to advance the use of AI/ML methods. Dr. Bui is Program Director of multiple separate NIH TL1/T15/T32s at UCLA in the areas of biomedical informatics and data science; Director for the Medical Informatics Home Area in the Graduate Program in Biosciences; Co-Director of the Center for SMART Health; and serves at the Senior Associate Director for Informatics for UCLA’s Clinical and Translational Science Institute (CTSI). He also Co-Chairs the University of California (UC) AI Council.
