Kent State University

What you'll study

This PhD programme combines advanced disciplinary coursework with sustained original research. Core study areas include infectious disease epidemiology, environmental and occupational hygiene, tropical and parasitic diseases, disease ecology, global health systems, and advanced biostatistics. Typical modules and topics you may encounter are:

• Advanced Epidemiology — study design, outbreak investigation, surveillance systems and causal inference.
• Infectious Disease Biology — pathogen biology, host–pathogen interactions and antimicrobial resistance.
• Tropical Medicine — parasitology, vector-borne disease ecology and clinical aspects of tropical infections.
• Environmental & Occupational Hygiene — exposure assessment, industrial hygiene principles and environmental determinants of health.
• Biostatistics & Research Methods — multivariable modelling, longitudinal and spatial analysis, and mixed-methods approaches.
• Global Health Policy & Ethics — health systems, interventions in low- and middle-income settings, and research ethics in vulnerable populations.
• Professional Skills — grant writing, scientific communication, teaching pedagogy and project management.

The programme structure typically involves an initial period of coursework, successful completion of qualifying and comprehensive examinations, and at least one major original research project resulting in a doctoral dissertation. Students conduct laboratory work, field studies or secondary-data research depending on their dissertation focus, and are expected to publish and present findings at national and international fora. Teaching or research assistantships form a common part of doctoral training.

Entry requirements

Applicants are normally expected to hold a relevant master's degree (for example in public health, epidemiology, biomedical sciences, or a related discipline) or a strong honours bachelor’s degree with substantial research experience. Typical requirements include:

• A demonstrated record of academic achievement (official transcripts).
• Research experience, including previous thesis work, publications, or laboratory/fieldwork experience.
• A personal statement outlining research interests and fit with faculty expertise.
• Curriculum vitae showing relevant professional and research activity.
• Letters of recommendation from academic or professional referees who can speak to research potential.
• Proficiency in English demonstrated by recognised tests where required for international applicants.

Applicants should identify potential supervisors and describe possible dissertation topics in their application. The programme may require an interview as part of the selection process. Specific minimum GPA thresholds, test score expectations and funding arrangements are detailed on the university’s admissions pages.

Career prospects

Graduates of this PhD typically move into roles that require high-level research skills, subject-matter expertise and the ability to translate findings into policy or practice. Common career pathways include:

• Academic positions (postdoctoral research, tenure-track faculty, teaching and research roles).
• Research scientist roles in public health agencies, national disease control programmes and international organisations.
• Technical and leadership positions in non-governmental organisations and humanitarian agencies engaged in tropical medicine and health systems strengthening.
• Scientific and regulatory roles in biotechnology, diagnostics and pharmaceutical sectors focused on infectious disease.
• Policy, surveillance and programme evaluation roles within government health departments and global health institutions.

Graduates are also prepared for consultancy, science communication and leadership posts within multidisciplinary teams tackling global health threats.
