Alex Bui, PhD

Director, Medical & Imaging Informatics Group
Director, Medical Informatics Home Area
Professor, Departments of Radiological Sciences, Bioengineering & Bioinformatics
David Geffen Chair in Informatics


Dr. Bui received his PhD in Computer Science in 2000, upon which he joined the UCLA faculty and MII. His research includes informatics and data science for biomedical research and healthcare in areas related to distributed information architectures and mHealth; data and probabilistic modeling methods, including machine learning and sequential decision making; 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 NIH institutes (NCI, NLM, NINDS, NIBIB). 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 is currently the Director of the NIH-funded Los Angeles PRISMS Center, a U54 focused on mHealth informatics. He is also a Program Director of three separate NIH T32s at UCLA in the areas of informatics, biomedical big data, and data science; and is Co-Director of UCLA CTSI's Informatics Program and the Center for SMART Health.
