Epidemiologic Research

Our epidemiologists seek answers to important health questions with real-world clinical relevance.

Investigators with the Division of Epidemiologic Research apply rigorous research methods to address important health questions that have the potential to change clinical practice and health care delivery. The division’s research portfolio spans the care continuum, from etiology and prevention to survivorship and quality of life.

Division investigators have expertise in traditional epidemiologic studies, post-marketing safety and effectiveness studies, and outcomes research. Current research areas include cancer, cardiovascular disease, COVID-19, diabetes, infectious disease, molecular epidemiology, orthopedics and bone health, perinatal health, pharmacoepidemiology, and vaccines.
