Gabriela Schmajuk, MD, MS

Associate Professor

Dr. Schmajuk is Chief of Rheumatology at the San Francisco VA Health Care System and an Associate Professor in the Division of Rheumatology, Department of Medicine at UCSF. She received her undergraduate degree from Harvard, her MD from the University of Pennsylvania, and her Masters in Epidemiology from Stanford. She joined the faculty after completing internal medicine residency at Brigham and Women's Hospital and fellowship in rheumatology at Stanford. She practices in the SFVA rheumatology clinic.

Dr. Schmajuk's research focuses on quality of care and patient safety in patients with rheumatic diseases. She co-directs the UCSF Rheumatology Quality and Informatics Lab (, an interdisciplinary group that uses health services research, informatics, and implementation science to inform national health care improvement initiatives. Her work specifically highlights and aims to attenuate disparities in care across sex, race/ethnicity, socioeconomic status, and health literacy. She uses a variety of "big data" sources, including Medicare and EHR data from the VA and the he American College of Rheumatology’s RISE registry, which aggregates and analyzes data from rheumatology practices around the country. She also has projects to use Health-IT to integrate patient reported outcomes into clinical encounters in rheumatology.

Dr. Schmajuk has served as PI of grants from the NIH/NIAMS, AHRQ, and VA HSR&D, and has earned several honors and awards for her work, including the Ephraim Engleman Award for Arthritis Research, and the J.V. Satterfield Excellence in Rheumatology Research Award from the Arthritis Foundation.
