PhD in Marine Life Sciences

Tuition comes to 4,811 USD per year.

Marine Life Sciences examines the organisms, ecosystems, and biological processes found in oceans and coastal waters, covering areas such as marine biology, ecology, aquaculture, and fisheries science. A doctoral program in this field at Jeju National University in Jeju, South Korea, takes advantage of the island's surrounding marine environment to support research on coastal and open-ocean life, from microorganisms to larger marine species. Doctoral candidates combine advanced coursework with independent dissertation research, which might involve field studies of marine ecosystems, laboratory analysis of marine organisms, or applied research into aquaculture and fisheries management. Students build skills in marine sampling and survey methods, laboratory techniques, and data analysis that support both academic research and applied work in fisheries and conservation. Because the program is taught in English, it is open to international students who want to conduct marine science research in a Korean coastal setting without a Korean-language prerequisite. The degree runs two years across four semesters, with entry available in March or September. Graduates commonly pursue careers in marine research institutes, government fisheries and environmental agencies, aquaculture industry roles, or academic positions, where doctoral-level training supports independent research into ocean ecosystems and their sustainable use. Jeju's marine environment, including its coastal waters and aquaculture activity, gives students a research setting closely tied to the subject matter of the program itself.
