Prince of Songkla University

What you'll study

The PhD (EVE) is a research‑led programme combining advanced coursework, methodological training and an extended independent research thesis. Core study areas typically include advanced environmental chemistry and microbiology, water and wastewater treatment technologies, air pollution control engineering, solid and hazardous waste management, environmental impact assessment and management, environmental systems modelling and risk assessment, and applications of GIS and remote sensing to environmental monitoring.

Students also receive training in research design and quantitative/qualitative methods, statistical modelling, experimental techniques, and scientific communication. The precise mix of taught modules and research activity is agreed with a supervisory team and tailored to the candidate's research topic; common elements include a literature review, a formal proposal, periodic progress assessments and an oral thesis defence.

• Advanced environmental engineering and science topics (water, air, soil, waste)
• Research methods, data analysis and modelling
• Environmental monitoring, remote sensing and GIS applications
• Policy, management and impact assessment in environmental decision‑making
• Original empirical or theoretical research culminating in a doctoral thesis

Entry requirements

Applicants are normally required to hold a relevant master's degree (for example, MSc or MEng) in environmental engineering, environmental science, civil engineering, chemical engineering, or a closely related discipline from an accredited institution. Candidates with exceptional professional experience and a strong publication record may also be considered.

Typical application materials include academic transcripts, a research proposal or outline of intended doctoral research, a curriculum vitae, and academic references. Evidence of English-language proficiency may be required where the applicant's prior education was not in English; acceptable evidence is determined by the university. Prospective students should also identify potential supervisors whose research interests align with their proposed topic, and meet any additional Graduate School requirements set by Prince of Songkla University.

Career prospects

Graduates from the PhD (EVE) programme pursue a wide range of careers. Common destinations include academic and research positions in universities and national research institutes, senior technical and leadership roles in environmental consultancies, and specialist posts within government agencies responsible for water resources, pollution control, waste management and environmental regulation.

Other career paths include roles in private industry (environmental management, sustainability and compliance), international organisations and NGOs working on environmental protection and climate resilience, and entrepreneurial ventures developing environmental technologies. The programme is particularly valuable for those aiming to lead multidisciplinary teams, design policy‑relevant research, or translate advanced environmental science into practical solutions for tropical and coastal ecosystems.
