The Environmental Science and Engineering PhD program focuses directly on many of KAUST’s research challenges. The results of such research may offer solutions to cleaning up excessive carbon dioxide levels, addressing ozone depletion, decontaminating the soil, and tackling some of the issues associated with climate change. KAUST is uniquely positioned to utilize high-performance computational technologies to confront these issues efficiently and effectively. This program comprises three tracks: Water Quality, Chemistry, and Treatment; Environmental Microbiology and Biotechnology; and Environmental Hydrology and Fluid Mechanics. Students entering the program enroll in a set of core courses and then take specialty courses in one of the three major tracks. The remaining courses are technical electives. The three tracks together cover the most important areas in Environmental Science and Engineering, and the core plus specialty courses and electives will equip a student for a successful and productive career in these fields.
