      Margaret C. Fang is an Associate Professor of Medicine at the UCSF and joined the UCSF Division of Hospital Medicine in 2003. She is a graduate of the Honors Program in Medical Education at Northwestern University Medical School and trained in internal medicine at the Beth Israel Deaconess Medical Center in Boston. Subsequently, she completed a General Medicine Fellowship at the Massachusetts General Hospital and a Masters of Public Health at the Harvard School of Public Health.

      Margaret is the Medical Director of the UCSF Anticoagulation Clinic and devotes the majority of her time towards evaluating the quality, safety, and outcomes associated with anticoagulation therapy, with a particular focus on how to optimize the use of anticoagulants among older adults. She is a member of the ATRIA Study Group, investigating thromboembolic and hemorrhagic outcomes in a cohort of people with atrial fibrillation as well as the lead investigator of the CVRN Venous Thromboembolism Study, a cohort of patients with venous thromboembolic disease. Other research projects include investigating the use of genomic testing to guide warfarin dosing, the use of antithrombotic therapy among people undergoing orthopedic surgery, and assessing trends in risk factors and outcomes related to acute stroke.
