Reza Yaesoubi, PhD, is an Associate Professor at the Philip R. Lee Institute for Health Policy Studies and the Department of Epidemiology and Biostatistics at the University of California, San Francisco. He is a health decision scientist whose research focuses on developing and applying analytical methods to inform data-driven and value-based decisions in clinical care, public health, and global health. His primary area of expertise lies in guiding decisions when evidence and data evolve too rapidly for static policies or guidelines to suffice—for example, during outbreaks of novel pathogens or the spread of antimicrobial resistance. He is also interested in advancing the theoretical and methodological foundations of adaptive decision-making and health care resource allocation.
