Ida Sim, MD, PhD is Associate Professor Medicine at the University of California, San Francisco, where she directs the Center for Clinical and Translational Informatics and is a primary care physician. Dr. Sim is an international leader in informatics for clinical research and evidence-based medicine. Her research centers on computational technologies for building the global, computable “human studyome,” in which the design and results of all human studies worldwide are made computable for large-scale data mining, synthesis, and re-analysis. Dr. Sim was also the founding Project Coordinator of the World Health Organization’s International Clinical Trials Registry Platform, which sets global standards for clinical trial registration and reporting. In addition to her informatics research, she has also conducted systematic reviews and has published on clinical trial reporting bias, new models of clinical trial publication, and the adoption of electronic health records in primary care practices for quality improvement. She serves on the editorial board of the Journal of Biomedical Informatics and on the Advisory Board for PLoS One, and was a member of the National Research Council report on Computational Technology for Effective Health Care. Dr. Sim is a recipient of United States Presidential Early Career Award for Scientists and Engineers (PECASE), and is an elected Fellow of the American College of Medical Informatics and an elected member of the American Society for Clinical Investigation.
