Cleo Maehara, MD

Project Manager



After graduating from medical school and completing a residency in diagnostic radiology, Cleo pursued a clinical fellowship in musculoskeletal and body imaging. He obtained his Master’s degree in informatics from Harvard Medical School. Currently, he leads a team of programmers, data analysts, and coordinators that form the Data Integration, Architecture and Analytics Group (DIAAG) at the UCLA Department of Radiological Sciences. The group designs, develops, implements, and maintains a medical research infrastructure and informatics platform to improve the quality and efficiency of the radiology services. His interests and expertise are in clinical and imaging informatics, data science and analytics, and healthcare interoperability and integration.
