What We Do

What We Do

The Division of Epidemiology improves wellbeing for all by conducting research that yields robust, actionable evidence that advances our understanding of health and disease in populations, and by preparing the next generation of epidemiology research leaders. Our faculty brings together diverse expertise including population, clinical, social, environmental, and behavioral sciences to address critical public health challenges, and to develop and test evidence-based solutions to real-world health concerns.

Sean Hennessy, PharmD, PhD

Director, Division of Epidemiology
Professor of Epidemiology & Systems Pharmacology and Translational Therapeutics

COVID-19 highlighted the critical role that epidemiologists play in improving global public health. Beyond the pandemic, epidemiologists bring a trademark focus on measurement, causal inference, research design, and evaluation of health and policy interventions to address all aspects of health, including diverse challenges such as climate change, health disparities, the opioid epidemic, and gun violence.

Uniquely positioned within Penn Medicine’s world-class medical school and collaborative multi-hospital health system, and with strong partnerships with the Children’s Hospital of Philadelphia, we work closely with our DBEI colleagues in the Biostatistics and Informatics divisions, and with collaborators from diverse fields across and beyond Penn to improve health for all by producing robust and actionable evidence informed by multiple perspectives, disciplines, and skills.

We are dedicated to preparing the next generation of epidemiology research leaders. By teaching and mentoring through Penn’s epidemiology training programs, our division continues to drive innovation in a changing world, and to pave the way for future scientific breakthroughs in population health at Penn Medicine and beyond.
