The major components of the M.P.H. degree in the General Epidemiology (G.E.) track include: the design of studies, the collection and analysis of data, and the interpretation of empirical findings. The G.E. track emphasizes training in basic principles and methods of epidemiology and biostatistics and their application to the study of health and disease in human populations. Students in the G.E. track have many opportunities to learn about diverse specialized sub-disciplines of epidemiology through classes, projects and a summer internship. Faculty research projects and internships cover topics including cancer, social determinants of health, infectious diseases (e.g., tuberculosis, influenza, waterborne infectious disease), chronic diseases (e.g., stroke, cardiovascular disease, metabolic diseases), reproductive health (birth outcomes, mid-life health among women), climate change and health, the microbiome, and health among diverse populations, including Native Americans and Arab Americans. The M.P.H. in G.E. is earned in either 60- or 42-credit hours, depending on previous training and degrees. The 42-credit program is intended for students already holding a doctoral degree (M.D., D.D.S., D.V.M., Ph.D.). Both programs provide students with the knowledge and skills required to practice epidemiology in diverse settings and positions of employment. Applicants to the program hold bachelor's degrees in fields including, but not limited to: biology, pre-med or pre-dental studies, nursing, zoology, microbiology, mathematics, psychology, sociology, and anthropology.
