Doctor of Philosophy

Ph.D. in Global Infectious Disease candidates will receive a unique combination of training that brings together science, health, technology, modeling, social sciences, economics and governance.  While doctoral students will specialize in particular areas, Infectious Disease Ph.D. candidates will learn about the multitude of ways to approach different aspects of infection prevention and control, including life science research, mathematical modeling of outbreaks, economic impacts of pandemics, and diplomacy to advance health outcomes.

Who should apply to the Ph.D. in Global Infectious Disease?

Individuals dedicated to finding solutions to how the world can better approach infectious diseases are perfect candidates. We are looking for students committed to understanding global infectious disease problems and to approaching them in an interdisciplinary fashion. Students will have an interest in topics ranging from global health security governance, to health delivery economics, to epidemiology, and mathematical modeling. Ph.D. candidates will become an expert in their research area of interest while gaining broad knowledge that can be applied to global infectious disease problems.

This program will prepare successful students to join a growing workforce and find employment in a variety of areas depending on their speciality. These may include federal, state or local health departments, multilateral organizations, advocacy organizations, global health implementers, pharmaceutical companies, and academia, among others. 

The Global Infectious Disease Ph.D. Program has equivalent basic admissions requirements as MS Students. There will be a strong preference for applicants that hold an advanced degree or significant experience in the field. Ph.D. candidates should be able to demonstrate a clear study path or intellectual journey towards their Ph.D. area of interest and demonstrate a history of success, for instance through relevant employment positions or publications. Applicants should have a background in basic science: admission requirements include one semester each of undergraduate biology, chemistry, and calculus or statistics. Students should have significant course experience in math and advanced statistics, as well as experience in computer programming. Students also will need coursework in economics and political science. Before acceptance, all strong applicant candidates will be required to have an interview with two or three members of the Admissions Committee. This can be completed either on site or via video-teleconference.


Students will spend their first year taking core courses that will immerse them in the Global Infectious Disease curriculum. These courses include: Infection and Immunity, Ethics, Biostatistics, Epidemiology, and either Policy Analysis, or Modeling Biological Systems (total 19 credits). Please see the Global Infectious Disease Master of Science for a list of courses to take.

Students will have the option of doing research rotations with potential mentors during the first 8 months of the program.  These rotations would start in September of the first year, but are not required. Students not electing to rotate can begin dissertation research in Year 1.

Students can take electives to provide more specific background related to dissertation research. The remainder of the 30 credit requirement will be determined in partnership with the candidate’s Advisory Committee and Thesis Adviser, based on the candidate’s background and research interests. Most of year 2 is spent performing research and developing a base of knowledge to write and defend the dissertation proposal, aka the comprehensive exam taken in year 3.

Candidates will take their Comprehensive Exam by December 1 of Year 3. This is a written dissertation proposal with oral presentation and defense to ensure research plan is sound and to assess the proposal for the level of effort and timeline proposed. We anticipate students being able to complete the Ph.D. program in 5 years.

Teaching Requirement

Teaching will be a requirement of the Global Infectious Disease Ph.D. program, to reflect this core skill. There are several different options to complete this requirement, including:

  • Serving as a teaching assistant for one semester.
  • For senior Ph.D. candidates, teaching an undergraduate class.
  • Designing and teaching a short course. For example: designing and teaching a module of the Global Infectious Disease Core Course. 


Internships are encouraged for Infectious Disease Ph.D. candidates without work experience, but are not a requirement of the program.  Internships can be conducted for credit (up to 3 credits max.), equivalent to at least 150 hours, with a written summary of the work. 

Financial Support

Candidates admitted to the program are offered five years of financial support.
