PhD in Marine Life Sciences

Tuition costs 6,640,000 KRW per year.

This combined master's and doctorate program in Marine Life Sciences at Jeju National University in Jeju, South Korea, allows students to progress from graduate coursework into doctoral research within a single continuous track rather than applying separately for each degree. Marine Life Sciences covers the organisms, ecosystems, and biological processes of oceans and coastal waters, including marine biology, ecology, aquaculture, and fisheries science, and Jeju's surrounding marine environment gives students direct access to coastal and open-ocean settings for their research. Students begin with foundational coursework and applied research training, then move into independent dissertation work as they advance through the program, building skills in marine sampling, laboratory analysis, and data interpretation that support both academic and applied marine science careers. Instruction is conducted in English, making the program accessible to international students who want an integrated pathway to a marine science doctorate without first needing Korean-language proficiency. The combined program takes four years across eight semesters, reflecting the extended timeline needed to move from initial graduate study through to a completed doctoral dissertation, and new students can begin in either March or September. Graduates typically pursue careers in marine research institutes, government fisheries and environmental agencies, aquaculture industry roles, or academic positions, arriving at these opportunities through a research trajectory that stays within one program rather than transitioning between separate master's and doctoral applications.
