University of Arizona

What you'll study

The programme combines advanced coursework, laboratory and field research, and a substantial original dissertation. Core topics typically include epidemiology and biostatistics, clinical and molecular aspects of infectious diseases, parasitology and vector biology, vaccine science and immunology, environmental and occupational hygiene, disease surveillance and outbreak investigation, and research ethics and global health policy. Students take seminars and journal clubs and complete practical training in laboratory methods (molecular diagnostics, pathogen culture, serology) and field methods (community-based surveys, entomological sampling, GIS and spatial analysis).

Structure normally involves intensive coursework and rotations in the first one to two years, followed by a qualifying or comprehensive exam to advance to candidacy. The major research phase is the design and execution of an original research project under a faculty supervisor, culminating in a written dissertation and oral defence. Training also emphasises grant writing, science communication and teaching experience.

Entry requirements

Applicants usually hold a relevant graduate degree (Master’s in public health, epidemiology, biomedical sciences, microbiology or a related field) or a strong honours Bachelor’s degree with substantial research experience. A demonstrated background in quantitative methods and laboratory or field experience in infectious disease research is highly desirable. Application materials generally include academic transcripts, a research statement or proposal that aligns with faculty expertise, a curriculum vitae, and at least two academic references. English language proficiency evidence is required for non-native speakers. Some programmes may request GRE scores or other standardised test results, though requirements vary by department.

Career prospects

Graduates move into academic and research positions in universities and research institutes, often leading independent research programmes in infectious or tropical diseases. Other common career paths include roles within national public health agencies, international organisations (for example WHO regional offices), non-governmental and humanitarian organisations, disease surveillance and outbreak response units, and clinical trials or vaccine development in the biopharmaceutical sector. Additional opportunities exist in policy advisory positions, global health programme management, and consulting on health systems strengthening and disease control strategies.

Why study at University of Arizona

The University of Arizona offers an interdisciplinary environment with strengths relevant to hygiene and tropical medicine across the Mel and Enid Zuckerman College of Public Health, the College of Medicine – Tucson and universitywide research institutes such as BIO5. Students benefit from collaborative laboratories, vector ecology and infectious disease research groups, and partnerships with regional public health departments and international collaborators that support fieldwork and applied research. The university’s location supports research on border health, zoonoses and vector‑borne disease ecology, and there are opportunities for training in both laboratory and community settings. Doctoral students typically receive mentoring from faculty with active grant portfolios and have access to teaching assistantships, research assistantships and institutional funding competitions to support their research training.
