University of Cincinnati

What you'll study

The PhD in Environmental Health combines advanced coursework, laboratory or field research and a sustained dissertation project. Students study core areas such as environmental toxicology, exposure science, environmental epidemiology, molecular and cellular mechanisms of toxicity, risk assessment, and application of quantitative methods to environmental health problems.

• Core coursework typically covers toxicology, exposure assessment, environmental epidemiology, biostatistics and research ethics.
• Advanced methods options often include environmental genomics/toxicogenomics, computational toxicology, geographic information systems (GIS) for exposure mapping, advanced statistical modelling, and dose–response modelling.
• Laboratory and field research emphasises mechanistic and translational projects; students normally join a faculty research group early and may undertake lab rotations where available.
• Seminars and teaching participation in departmental seminars and contribution to teaching or mentoring undergraduate/graduate students is expected as part of professional development.
• Qualifying exams and dissertation progression includes passing qualifying or comprehensive exams, proposing a dissertation, conducting original research under faculty supervision and defending a written dissertation.

Entry requirements

Applicants are normally expected to hold a recognised bachelor’s degree in a relevant discipline (for example biology, chemistry, toxicology, environmental science, public health, epidemiology, engineering or a related quantitative field). A relevant master’s degree can be advantageous but is not always mandatory if the applicant demonstrates strong academic preparation and research experience.

• Academic record: strong undergraduate performance (or graduate GPA where applicable) and coursework in life sciences, chemistry, mathematics/statistics or related areas.
• Research experience: prior laboratory, field or analytical research experience and evidence of the ability to undertake independent research (such as a thesis, publications, conference presentations or detailed research statements).
• References: typically two to three academic or professional references who can comment on research potential.
• English proficiency: for applicants whose first language is not English, satisfactory scores in an approved English language test are required in line with university policy.
• Additional materials: a statement of purpose outlining research interests and fit with faculty, curriculum vitae, and in some cases a writing sample or sample of scholarly work. GRE requirements vary over time and by programme — applicants should check current departmental guidance.

Career prospects

Graduates of the PhD in Environmental Health pursue a range of research and leadership careers. The programme prepares students for roles that require deep expertise in environmental health science, quantitative methods and research translation.

• Academic careers: tenure‑track faculty positions, postdoctoral research, and university research scientist roles focused on toxicology, exposure science, epidemiology and related fields.
• Government and regulatory agencies: scientist and policy roles in national and state public health agencies, environmental protection agencies, and regulatory bodies involved in risk assessment and environmental monitoring.
• Industry and consulting: positions in environmental and occupational health consulting, chemical and pharmaceutical companies, industrial hygiene, and environmental risk assessment and compliance.
• Non‑profit and international organisations: research and programme roles in NGOs, public health organisations and international agencies addressing environment and health issues.
• Clinical and translational roles: opportunities for interdisciplinary work with clinical researchers, particularly in exposure‑related disease mechanisms and community health studies.
