Upon completing the requirements for the PhD in Epidemiology, graduates are able to:

1. formulate research hypotheses that can be evaluated through empirical epidemiologic investigation
2. critically evaluate the advantages and disadvantages of epidemiologic study designs applied to particular etiologic associations
3. analyze and interpret epidemiologic studies using appropriate methods
4. explain the theoretical underpinnings of epidemiology, including new and traditional study designs
5. demonstrate understanding of sources of bias and approaches to evaluating and controlling bias
6. demonstrate proficiency in data collection, data analysis, and written summaries of statistical analyses
7. demonstrate expertise in at least one substantive area of epidemiology and apply that expertise to preparation of the dissertation proposal
8. perform all the steps of conducting a hypothesis-driven epidemiologic study, from developing hypotheses, to designing, analyzing, and interpreting results, to writing up findings in the form of a publication-quality manuscript, as demonstrated by the PhD dissertation, which requires three manuscripts judged to be suitable for publication.

Students complete 32 credits beyond the master’s degree. It is expected that at least 24 of these courses be from the epidemiology and biostatistics course offerings at the School of Public Health. Students may also choose from other courses offered at the School and pertinent graduate courses at Boston University. The intent of the coursework is to provide a firm foundation in epidemiologic principles and methods, biostatistic methods, and general public health knowledge.

Qualifying Exams

Students must pass comprehensive written examinations in epidemiology and biostatistics, to evaluate their readiness to begin dissertation research.

Dissertation

Students are required to develop a written proposal outlining the nature of their dissertation research. The dissertation is prepared and written under the direction of the candidate’s dissertation committee (comprised of the dissertation chair and at least two other members). When the dissertation is completed, the candidate defends their work before the dissertation committee and other faculty.

Our PhD students have researched a wide array of dissertation topics, such as:

• Maternal Medical History, Psychosocial Stress, and Birth Outcomes
• Environmental Heat in Relation to Maternal and Infant Health Outcomes
• Substance Use Among LGB Populations: The Role of Neighborhood, School and Family
• Methods to Predict and Explain New-Onset and Ongoing Depression in National Guard Members: A Lifecourse Perspective
• Applications of Big Data Approaches to Topics in Infectious Diseases Epidemiology
• Male Risk Factors for Subfertility: A Prospective Cohort Study
• Exploration of Structural and Statistical Biases in the Application of Propensity Score Matching to Pharmacoepidemiologic Data
• Examining Outcomes Associated with a Community Intervention on Smoking Cessation in a Low-Income Population
• Pregnancy Associated Changes in Maternal Nutritional Status
• Evaluating South Africa’s Antiretroviral Treatment Guidelines
• Impact of Physical Function on Health Outcomes in Older Community-Dwelling Women, Accounting for Age, Competing Risks, and Time-Varying Exposure
• Effects of Common Pharmacologic Agents on Reproductive Outcomes Among Male and Female Pregnancy Planners
• In Vitro Fertilization: Investigating the Risk of Ischemic Placental Disease and Novel Methods for Quantifying Success
• Environmental and Psychosocial Risk Factors for Sub-Fertility
• Iron Deficiency in Blood Donors: Causes, Symptoms, and Mitigation Strategies

Seminars, Journal Clubs, Etc.

Students attend monthly doctoral seminars conducted throughout the academic year. An important purpose of the seminars is for doctoral students to present their dissertation research in progress. These presentations provide an excellent forum for sharing research with fellow student and faculty colleagues. Other topics covered in the doctoral seminars may include: professional conduct, grant writing, networking, etc.

A journal club is organized and conducted by the doctoral students.

Teaching Opportunities

The Epidemiology PhD program is committed to providing doctoral students with opportunities for teaching and to fostering the development of their teaching skills. Most of the students enrolled in the program serve as Teaching Assistants. After gaining experience as a TA, interested doctoral students are offered the chance to lecture in a course. Students also have access to teaching workshops sponsored by the Boston University Center for Excellence and Innovation in Teaching.

Time to Completion

Students who matriculated into the program between 2010 and 2015 have had an average length to completion of 5.1 years (range, 3.5-7.5 years), with 70% completing their training in five years or less.

Between 2016 and 2020, 24 students matriculated into the Epidemiology Doctoral Program. During this period, the average annual acceptance rate was 7%.
