About this image…

The goals of doctoral training with a concentration in EMD are to provide a current theoretical and practical base of epidemiological and microbiological principles, to master research methods, and to apply these skills to investigations of the biology of infectious organisms of public health importance and the epidemiology of the diseases they cause. The approach is multidisciplinary. It includes ecological, clinical, cellular, immunologic and molecular aspects of infectious diseases, their causative agents, vertebrate hosts, and vectors. In addition, opportunities exist for Ph.D. training through interdepartmental programs in which YSPH faculty participate, such as the Microbiology and Immunobiology tracks of the Biomedical and Biological Studies program.

Applicants should have a bachelor's degree with a concentration in any of the biological sciences. Students with degrees in chemistry, physics, engineering or medicine are also encouraged to apply. Preparation in elementary calculus, elementary physics, inorganic and organic chemistry, statistics or advanced mathematics is desired. A master's degree is not required to apply for this program. Complete GRE test scores are required.

Although courses in epidemiology, microbiology and biostatistics are strongly recommended, there is no general required curriculum. A faculty advisor is assigned at the time the student matriculates. Each student plans, with the advice of the faculty advisor and the department representative to the Graduate Studies Executive Committee, a specific program that includes courses, seminars, laboratory rotations, and independent readings all tailored to the individual needs and career goals of the student. The plan is outlined as early as possible in the first semester of graduate study. A program of course work will most often include biostatistics, epidemiology, microbiology, as well as complementary courses offered in the basic biomedical sciences in other departments of the University. All students are required do three semester long laboratory rotations, each with a different principal investigator. After successful completion of the qualifying examination and submitting a prospectus, students are admitted to candidacy for the Ph.D. From this point students work exclusively on their dissertation research, culminating in the presentation of a thesis to the Yale faculty for examination.
