Oanh Nguyen, MD, MAS

Asst Professor In Residence

Dr. Nguyen’s research is focused on understanding and optimizing hospital care in safety-net settings and developing pragmatic approaches to addressing social determinants of health, particularly on the development and evaluation of transitional care strategies that address social vulnerabilities among individuals with complex medical needs.

Her current work, funded through the National Heart, Lung, and Blood Institute, seeks to develop strategies to predict, understand, and address coexisting social vulnerabilities among adults hospitalized with congestive heart failure or ischemic heart disease at high risk for readmission.
