David Larson
Professor of Radiology (Pediatric Radiology)
On Partial Leave from 01/15/2026 To 05/15/2026BioDavid B. Larson, MD, MBA, is Professor of Radiology (Pediatric Radiology) in the Department of Radiology at Stanford University. His career is focused on managing and improving complex sociotechnical healthcare systems to drive continuous operational improvement for the benefit of patients and clinicians. His research and leadership activities span the sociotechnical spectrum, from the development of process control systems that optimize CT radiation dose to transitioning the field of radiology from "peer review" toward "peer learning" to foster a more collaborative and constructive work environment.
He has founded and directed numerous improvement programs at Stanford and beyond, including Stanford’s Realizing Improvement through Team Empowerment (RITE) program, the Clinical Effectiveness Leadership Training (CELT) (program co-founder), Stanford Medicine's Improvement Capability Development Program (ICDP), and the Stanford Medicine Center for Improvement's (SMCI's) Advanced Course in Improvement Science (ACIS). He is also the founder and co-director of the American College of Radiology's (ACR's) Learning Network, its various Improvement Collaboratives, and the ImPower improvement training and project support program.
Dr. Larson served for over 10 years in various senior leadership roles in the Stanford Department of Radiology, including Associate Chair for Performance Improvement, Vice Chair for Education and Clinical Operations, Executive Vice Chair, and Acting Chair. He currently serves as the Director of the Stanford Radiology AI Development and Evaluation (AIDE) Lab. He also serves as the Medical Director of Performance Improvement at Stanford Health Care.
Dr. Larson has applied his experience to advance the thinking and application of systematic improvement methods in the field of radiology. He is the founder and program chair for the annual Radiology Improvement Summit held annually at Stanford, which began in 2016. He serves on the Board of Trustees of the American Board of Radiology, overseeing quality and safety, and on the Board of Chancellors for the American College of Radiology as the chair of the ACR's Commission on Quality and Safety.
Prior to his position at Stanford, Dr. Larson was the Janet L. Strife Chair for Quality and Safety in Radiology and a faculty member of the James M. Anderson Center for Health Systems Excellence at Cincinnati Children’s Hospital in Cincinnati, Ohio. He holds MD and MBA degrees from Yale University and completed his pediatric internship and radiology residency and fellowship at the University of Colorado Health Sciences Center in Denver, Colorado. Dr. Larson practices clinically at Lucile Packard Children's Hospital at Stanford. -

Rosita Primavera
Basic Life Research Scientist, Rad/Pediatric Radiology
BioDr. Rosita Primavera is a Basic Life Research Scientist at Stanford University in the Department of Radiology/Pediatric Radiology. With an MD in Chemistry and Pharmaceutical Technology and a PhD in Cellular and Molecular Biotechnologies, she brings a robust educational background to her research endeavors. Dr. Primavera has extensive experience in developing nano- and micro-drug delivery systems (DDS) as well as 3D platforms aimed at treating various diseases.
Her training includes a variety of techniques for creating drug delivery systems and 3D platforms, utilizing both synthetic and natural materials, and employing methods such as top-down and bottom-up fabrication. Over the past few years, Dr. Primavera's research interests have increasingly focused on diabetes. She has received extensive training in handling and processing pancreatic islets from multiple sources, including mice, rats, and humans, equipping her with the expertise needed to conduct both in vitro and in vivo experiments involving diabetic animal models. Dr. Primavera is focused on developing an on-command system that mimics pancreatic islet function. Her current research further investigates the role of 3D bioscaffolds in pancreatic islet transplantation, along with the involvement of mesenchymal stem cells in diabetes treatment. She is particularly interested in innovative cellular approaches, such as co-transplantation of islets alone, within cutting-edge bioscaffolds, or in conjunction with stem cells. Through her work, Dr. Primavera aims to enhance therapeutic strategies for diabetes and improve patient outcomes. -
Raheleh Roudi
Basic Life Research Scientist, Rad/Pediatric Radiology
