Clarkson University

What you'll study

The PhD in Environmental Health combines advanced coursework with independent research to develop expertise in exposure science, environmental toxicology, epidemiology and the environmental fate of contaminants. Core topics typically include exposure assessment and modelling, environmental chemistry, toxicological mechanisms, biostatistics and study design, risk assessment and environmental policy. Students also take methods-focused modules in analytical techniques, environmental monitoring, geospatial analysis (GIS), and laboratory/field methods for measuring chemical, biological and physical stressors.

The programme structure centres on a set of doctoral-level courses, original dissertation research supervised by faculty, seminars and professional development activities. Early years emphasise coursework and preparation for a qualifying or comprehensive examination; later years focus on research, publication and dissertation defence. Students are expected to present at conferences, publish in peer-reviewed journals and may undertake teaching or mentoring duties as part of their training.

Entry requirements

• Academic background: A relevant master's degree is preferred, though exceptional candidates with a strong bachelor’s degree in environmental science, public health, toxicology, chemistry, biology, engineering or a closely related field will be considered.
• Research experience: Demonstrated research potential through a thesis, publications, laboratory experience or relevant work is highly desirable.
• Supporting documents: Applicants should supply transcripts, a statement of research interests, a CV, and strong letters of recommendation that speak to research ability and fit with the programme.
• English proficiency: Non-native English speakers must meet the university’s English language requirements.
• Fit with faculty: Admission normally requires alignment between the applicant’s research interests and the expertise of potential faculty supervisors within Clarkson’s environmental and health-related research groups.
