PhD in Department of Mathematical Sciences

Tuition is 5,565 USD per year.

Mathematical sciences encompass pure and applied mathematics, including algebra, analysis, geometry, probability, statistics, and numerical methods, along with their applications to science, engineering, and computation. The Department of Mathematical Sciences at the Ulsan National Institute of Science and Technology (UNIST) offers a doctoral program for students aiming to conduct independent mathematical research, whether in theoretical areas or in applied fields such as mathematical modeling, optimization, and data analysis. A doctorate in mathematical sciences trains candidates to formulate rigorous proofs, develop new theoretical frameworks, and apply mathematical reasoning to problems drawn from physics, engineering, finance, or computer science. Career paths for graduates include university teaching and research, positions at research institutes, and analytical or quantitative roles in industries such as finance, technology, logistics, and data science, where mathematical modeling skills are in steady demand. UNIST is located in Ulsan, South Korea, and this PhD program runs over eight semesters, with intakes in March and August. All coursework and thesis supervision are conducted in English, allowing international applicants to pursue advanced mathematics study without a Korean-language prerequisite. Students generally begin with graduate-level coursework covering core areas of mathematics, then move into specialized research under a faculty advisor, culminating in a dissertation that must present original results. Along the way, doctoral candidates are expected to present their work at seminars and conferences and to pass qualifying examinations that confirm readiness for independent research.
