Much of clinical and translational research today depends on knowledge of epidemiology and biostatistics including study design, population sampling, identifying and reducing sources of bias, advanced biostatistical methods (regression analyses, survival analyses, risk prediction/prognostication) along with other methods widely used in clinical research (systematic literature reviews, meta-analyses, clinical trials, genetic epidemiology). The MS program provides intensive training in epidemiology and research methods for scientists and health care professionals who seek to conduct epidemiology/clinical epidemiology research. The main difference between the MS in Chronic Disease Epidemiology and the MPH in Chronic Disease Epidemiology is that the MPH is a two-year degree that provides broad training in public health (including biostatistics, health policy, environmental health sciences, and social and behavioral sciences), whereas the MS is a one-year degree that provides specialized training in epidemiology, more advanced biostatistics, and research methods.

The MS program is particularly well-suited for clinical fellows or junior faculty, who often fund their program through a K award. While this program is designed for individuals with a doctoral-level degree in a field related to health (e.g., MD, DVM, DDS, or PhD in the biological, behavioral, or social sciences), exceptional applicants without a prior doctorate but with a strong background in a biological or social science are also eligible to apply. Applicants should have one year of coursework in statistics or the equivalent prior to enrolling in this program; this requirement may be met through a Yale School of Public Health intensive biostatistics course taken during the summer before enrollment. This degree can be completed in one year of intensive full-time study, or for working professionals, a more flexible timeline can be arranged.

Like the PhD, the MS in Public Health is offered through the department’s affiliation with the Graduate School of Arts and Sciences. 

  • Applicants must submit GRE General Test score (less than 5 years old) to the Graduate School of Arts and Sciences (institution code 3987; no department code is required). 
  • Only applicants to the MS in Chronic Disease Epidemiology may submit MCAT scores in lieu of the GRE.
  • The Test of English as a Foreign Language (TOEFL) is required of all applicants whose native language is not English. This requirement is waived only for applicants who will have received a baccalaureate degree, or its foreign equivalent, prior to matriculation at Yale, from a university or college where English is the primary language of instruction. TOEFL scores should also be sent to institution code 3987.
