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.
