Dr. Oanh Kieu Nguyen, M.D., M.A.S. is an Assistant Professor in the Division of General Internal Medicine (Department of Internal Medicine), with a secondary appointment in the Division of Outcomes and Health Services Research (Department of Clinical Sciences). Seeking to understand determinants of human behavior at both the microscopic and macroscopic levels, she earned her B.S. in both neuroscience and political science from UCLA. She completed her medical school training at UCSD. Drawn by the opportunity to serve the underserved at Parkland, she subsequently completed her internal medicine residency training at UT Southwestern Medical Center. Following her residency, she worked as a hospitalist at Parkland and research associate at PCCI (formerly the Parkland Center for Clinical Innovation) before undergoing additional training via the Primary Care Research Fellowship at UCSF, where she earned her Master's degree (Master of Advanced Studies, M.A.S.) in clinical research with specialization in implementation science.

Dr. Nguyen joined the faculty at UT Southwestern in 2013 and is a health services researcher and a practicing general internist who provides care in both inpatient and outpatient care settings at Parkland Health and Hospital System, Dallas County's health safety net. Influenced by her commitment to social justice and health equity, her research agenda focuses on improving health care delivery for underserved populations through addressing unmet health-related social needs to improve overall health. Dr. Nguyen’s research is currently supported through the National Institutes of Health by the National Heart, Lung and Blood Institute. She has methodologic expertise in the use of electronic health record (EHR) data and other large datasets for research, development of readmission risk prediction models, qualitative and mixed methods research, and conducting systematic reviews.

In addition to her research, she teaches health policy to students in the UTSW Master’s program for Clinical Sciences, as well as to internal medicine residents. She is the faculty advisor for the UTSW Health Advocacy Student Interest Group. She is #ProudtobeGIM, and co-founded and co-directs the General Internal Medicine Resident Interest Group at UT Southwestern. Nationally, she is an Associate Editor for the Journal of Hospital Medicine.
