Ph.D. in Environmental Science normally lasts 3-5 years and focuses on advanced study on key environmental challenges. The program includes difficult courses in ecological theory, environmental policy, sustainability, and advanced research methods. Students conduct original research, which frequently includes fieldwork, data analysis, and interdisciplinary cooperation, culminating in a dissertation that adds to the body of knowledge in the discipline. Candidates may study climate change, conservation biology, environmental chemistry, or ecosystem management. The curriculum prepares graduates for positions in academia, government agencies, non-profit organizations, and the commercial sector, with an emphasis on practical solutions to environmental issues.
