University of Iowa

What you'll study

The PhD in Environmental Health emphasises interdisciplinary research into environmental determinants of health. Core areas of study typically include exposure science, environmental epidemiology, environmental toxicology, risk assessment, and statistical methods for environmental health research. Students take advanced coursework in biostatistics and study design, environmental fate and transport, occupational/environmental hygiene, molecular and mechanistic toxicology, geographic information systems (GIS) for exposure mapping, and policy and regulatory frameworks affecting environmental health.

Programme structure combines formal coursework, advanced methods training, teaching experience, qualifying examinations and an original doctoral dissertation. Early years focus on coursework and laboratory or field training; subsequently students concentrate on dissertation research under the supervision of a primary advisor and a dissertation committee. Many students also complete practicum or collaborative projects with public health agencies or industry partners as part of applied training.

• Advanced epidemiology and exposure assessment
• Environmental toxicology and molecular methods
• Biostatistics and research methods for environmental data
• Risk assessment, environmental policy and regulatory science
• Lab- and field-based methods, including sampling and analytical techniques
• Professional development: grant writing, scientific communication, and teaching

Entry requirements

Applicants are expected to hold a relevant graduate degree (master's preferred) or a strong bachelor’s degree in a related discipline such as public health, environmental science, epidemiology, toxicology, biology, chemistry, engineering or a closely related field. Competitive candidates will demonstrate prior research experience, quantitative skills, and clear potential for independent research.

Typical application materials include:

• Official academic transcripts from all post-secondary institutions
• Curriculum vitae or résumé highlighting research experience
• Statement of purpose describing research interests and intended faculty mentor(s)
• Letters of recommendation (generally three) from academic or research supervisors
• Samples of research work or publications, if available
• Proof of English language proficiency for international applicants where required

Admission is determined holistically; exact prerequisites, minimum GPA expectations and any testing requirements are provided by the graduate admissions office and the Department of Occupational and Environmental Health.

Career prospects

Graduates are prepared for a wide range of careers in research, practice and policy. Common career paths include academic faculty positions and postdoctoral research, scientific and leadership roles in government public health and environmental agencies, positions in regulatory science and risk assessment, and technical roles in environmental consulting and industry. Other graduates work for non-governmental organisations, international health organisations, and laboratory or analytical service providers where they apply expertise in exposure science, toxicology, epidemiology and environmental monitoring.
