Georgia Institute of Technology

What you'll study

This PhD is research-led and integrates environmental science, toxicology, exposure assessment, epidemiology, risk analysis and quantitative methods. Coursework typically covers advanced environmental toxicology, exposure science and monitoring, environmental epidemiology, biomarker analysis, statistics and data science, atmospheric and water quality processes, environmental fate and transport, and environmental risk assessment.

Programme structure combines a period of formal coursework and method training with intensive independent research. Early years focus on core courses, laboratory or field-method training, and seminars. Students sit qualifying or candidacy examinations to demonstrate mastery of the discipline and then concentrate on an original dissertation under the guidance of a faculty advisor. Typical components include:

• Core and elective coursework in toxicology, exposure assessment, epidemiology, and quantitative methods
• Research rotations or practicum opportunities in laboratories, field sites or with partner agencies
• Teaching or mentoring experience as part of professional development
• Doctoral qualifying/candidacy assessment and a dissertation based on original research
• Participation in seminars, journal clubs and interdisciplinary centres

Entry requirements

Applicants are expected to hold a relevant postgraduate degree (master's or equivalent) or a strong bachelor's degree in environmental science/engineering, public health, biology, chemistry, toxicology, epidemiology, biostatistics, or a closely related discipline. Successful candidates typically demonstrate:

• Strong academic performance in prior degree(s)
• Research experience such as a master's thesis, laboratory work, field studies or publications
• A clear research statement that aligns with faculty expertise at Georgia Tech
• Letters of recommendation from academic or professional referees who can attest to research potential
• Proficiency in quantitative methods and statistics, or evidence of willingness to undertake training in these areas

Additional requirements for international applicants include proof of English language proficiency where required. The programme may request GRE scores or other evidence of preparedness on a case-by-case basis; applicants should consult departmental guidance for current requirements.

Career prospects

Graduates from an Environmental Health PhD pursue diverse careers in academia, government, industry and the non-profit sector. Common pathways include:

• Academic and research positions in universities and research institutes conducting environmental health science
• Scientific and policy roles in public health agencies, regulatory bodies and environmental protection organisations
• Technical and leadership roles in environmental consulting firms focused on exposure assessment, risk management and remediation
• Research scientist or environmental health specialist positions in industry (pharmaceuticals, energy, manufacturing) and in biotechnology or environmental technology companies
• Positions with international organisations and non-governmental organisations working on environmental health, pollution control and community health interventions
