Improving population health through epidemiology research and preparing the next generation of epidemiologists.
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.
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.

Alexis Ogdie, MD, MSCE, selected Executive Leadership in Academic Medicine Fellow.
Penn researchers, including Drs. Halpern and Harhay, found that electronic nudges improved end-of-life care discussions in ICUs, increasing hospice discharges and comfort-care orders without shortening hospital stays.
Penn Medicine researchers, including M. Kit Delgado, MD, MS, found that small financial incentives using connected car data significantly increased seatbelt use—even after rewards ended—offering a low-cost, scalable strategy to improve driver safety nationwide.
Elizabeth Diemer, PhD, brings expertise in causal inference and mental health epidemiology to her new role as an Assistant Professor of Epidemiology within the department.
Research Project Manager
For almost three years, Kacie Bogar, MS has served as a Research Project Manager for the Center for Real-World Effectiveness and Safety of Therapeutics (CREST) and the Epidemiology division. In this role, she supports and collaborates with CREST investigators to produce research in the areas of drug-drug interactions, stimulant overdose trends, and environmental pharmacoepidemiology. In this Q&A, Bogar shares her interest in health policy; how she leverages a background in research and public health; and her experiences being a part of the DBEI and Penn community.
