Epidemiology and Biostatistics

Public Health was defined by C-E.A. Winslow as the science and the art of preventing disease, prolonging life, and promoting physical health and efficiency through organized community efforts with the goal of enabling every citizen to realize his/her birthright of health and longevity. 

The disciplines of epidemiology and biostatistics are essential to achieving the goals of public health, and combining these two disciplines in a single department creates synergies for both training and research. Epidemiologists study the distribution and determinants of health and disease in populations.  Biostatisticians develop and apply statistical theory, methods and techniques to public health research data and the planning, implementation and evaluation of public health programs. Given the strong overlap, epidemiologists and biostatisticians often collaborate to work toward the shared goal of generating and analyzing data to advance the public’s health.

Within the department, the degree programs are administered under two separate streams, the Division of Epidemiology and Division of Biostatistics.

Find out more about the department and what we offer in our welcome from the Chair.

Degrees Offered

We offer eight advanced degrees in epidemiology and biostatistics. Each graduate degree has specific application deadlines and requirements.
