Biography
Dr. Sae-Hwan Park is Associate Director of Research in General Internal Medicine at Penn Medicine. His work spans healthcare AI, health equity, clinical prediction, digital health, and pragmatic clinical research, with a particular interest in how data-driven methods and health system interventions can improve the quality and equity of care.
His research examines the performance and fairness of healthcare algorithms across heterogeneous patient populations. Current areas of work include racial and geographic disparities in clinical risk models, race-neutral approaches to incorporating social determinants of health, model performance drift, and statistical methods for evaluating predictive models when underlying risk distributions differ across populations.
Dr. Park also contributes to behavioral and health-system interventions conducted through Penn Medicine, including randomized studies of vaccination, statin prescribing, and cancer screening. His work in digital health includes the use of wearable-device data to understand and predict post-discharge outcomes. Across these projects, he combines statistical analysis, clinical data engineering, and reproducible research methods to support studies using electronic health records, Medicare claims, and other real-world healthcare data.
He holds a PhD in Public Health Science with a concentration in Health Outcomes Research, an MSc in Policy Economics, a bachelor’s degree in Electrical Engineering, and a Master of Applied Science in Computer Science from the University of Pennsylvania. His interdisciplinary training informs his work at the intersection of quantitative methodology, health services research, and healthcare technology.
