PhD in Population Health Science

Students gain the advanced research, analytic, and communication skills needed to address urgent health challenges in Mississippi and beyond—while contributing meaningful scholarship to the growing field of population health science.

A Doctoral Degree Designed for Impact

This is a program for students who want to do more than study health problems—they want to help solve them. The PhD in Population Health Science prepares graduates to investigate the clinical, social, environmental, and structural factors that influence health and to develop evidence-based strategies that improve outcomes across populations.

With a strong emphasis on knowledge translation, the program prepares students to move research into action—connecting data, discovery, and decision-making in ways that matter in the real world.

Interdisciplinary Training for a Complex World

Population health challenges do not fit neatly into a single discipline, and neither does this degree. All PhD students major in the interdisciplinary field of Population Health Science, building expertise across research design, health determinants, disparities, systems thinking, and applied problem-solving.

Students also have the flexibility to shape their training through elective coursework in areas such as vulnerable populations or science communication and dissemination, allowing them to align the degree with their professional goals and research interests.

Skills That Set Graduates Apart

PhD students develop the ability to:

• Critically evaluate and synthesize scientific literature

• Collect, manage, analyze, and interpret population-level data

• Design rigorous studies focused on health outcomes, determinants, and disparities

• Conduct community health needs assessments

• Evaluate the health impact of policies and programs

• Develop proposals for population health interventions and program evaluation

• Communicate research clearly to academic, clinical, community, and policy audiences

• Work effectively in interdisciplinary teams

• Apply systems thinking to complex health challenges

• Use evidence to improve healthcare delivery, health systems, and population outcomes

These skills prepare graduates for careers in research, academia, government, healthcare systems, nonprofits, and community-based organizations.

A Strong Academic Pathway

Students complete a minimum of 71 credit hours and can typically finish the program in approximately five years. The curriculum includes foundational and advanced coursework, a written qualifying examination, a dissertation proposal defense, and an original dissertation with real-world relevance.

This is a research degree built for students who are ready to make a distinctive contribution to the field. Graduates are expected not only to master existing knowledge, but also to produce original research and demonstrate the ability to conduct independent investigation.

Mentored Research with Real-World Application

Under the guidance of faculty mentors and a doctoral dissertation committee, students develop and carry out an original research project that addresses important population health questions. Once approved by the dissertation committee and the University of Mississippi Medical Center Institutional Review Board (IRB), students move forward with dissertation research that is designed to inform practice, policy, and future scholarship.

The program culminates in a formal written dissertation and a public oral defense, giving students the opportunity to present their work to the wider university community.

An Accelerated Path for Future Physician-Scientists

The MD/PhD track in Population Health Science offers an accelerated path for medical students who want to pair clinical training with advanced research preparation. This seven-year program is designed to develop physician-scientists who can investigate the clinical and non-clinical determinants of health and lead efforts to improve outcomes across populations.

The program follows this structure:

• M1-M3: First three years of medical school

• P1-P3: Three years of graduate study in Population Health Science

• M4: Final year of medical school

During the PhD phase, students complete the remaining doctoral coursework and dissertation research. The MD/PhD track is ideal for students who want to build careers that combine medicine, research, and population-level impact.

Why Choose SOPH?

At the John D. Bower School of Population Health, students benefit from a learning environment that is rigorous, collaborative, and mission-driven. Faculty are deeply engaged in research and practice, and students are trained to think critically, work across disciplines, and apply evidence to some of the most pressing health issues facing communities today.

For students who want to lead through research, influence systems, and improve health on a broader scale, the PhD in Population Health Science offers a strong and purposeful path forward.
