Materials Science and Engineering focuses on understanding, designing and developing materials for different technological applications.
Students can study materials such as metals, polymers, ceramics and advanced materials, as well as their properties, processing and applications.
The field is important in industries ranging from electronics and semiconductors to energy, manufacturing and aerospace.
POSTECH, for example, offers Materials Science and Engineering as one of its undergraduate and graduate fields.
7. Environmental Science and Engineering
If you are interested in climate, pollution control, water resources, waste management or sustainable technologies, Environmental Science and Engineering may be worth considering.
Programmes in this area can combine science and engineering approaches to environmental challenges, including water treatment, air pollution, waste management and environmental sustainability.
Some Korean graduate programmes also offer specialised areas such as environmental science and engineering, including water and energy-related research.
8. Biotechnology and Life Sciences
Biotechnology and Life Sciences are suitable options for students interested in biology and its technological applications.
Depending on the programme, students may study molecular biology, genetics, microbiology, biochemistry, bioengineering and other areas of biological science.
These fields can lead to opportunities in biotechnology, pharmaceuticals, healthcare research, food technology and scientific research.
POSTECH, for example, lists Life Sciences among its undergraduate and graduate academic fields.
9. Mathematics and Applied Mathematics
Mathematics is another STEM discipline available to international students in South Korea.
Students can explore areas such as pure mathematics, statistics, mathematical modelling, computational mathematics and applied mathematics, depending on the programme.
A mathematics degree can provide a foundation for careers and further study in data science, finance, technology, research, engineering and academia.
POSTECH offers Mathematics at both undergraduate and graduate levels.
10. Physics
Physics is a strong option for students interested in understanding how the physical world works and applying scientific principles to technological problems.
Students may study areas such as mechanics, electromagnetism, quantum physics, materials physics, computational physics and other specialised fields.
Physics can provide a foundation for careers or further research in areas such as technology, energy, materials, electronics and scientific research.
POSTECH is among the Korean institutions offering Physics as an academic field for undergraduate and graduate students.
EXPLORE SCHOLARSHIPS
Scholarship Opportunities to Study in South Korea
South Korea offers several scholarship opportunities for international students, ranging from fully funded government scholarships to university-based tuition waivers and living stipends. The Korean government’s official Study in Korea platform notes that many Korean universities, foundations and corporations offer scholarships to international students, with university scholarships commonly covering 30% to 100% of tuition fees, depending on the institution and the student’s academic performance.
1. Global Korea Scholarship (GKS)
The Global Korea Scholarship (GKS) is the major Korean government scholarship for international students. It supports international students pursuing degree programmes in South Korea and can provide substantial financial support, including tuition, living expenses, airfare and Korean-language training, depending on the scholarship category and level of study.
For graduate applicants, the 2026 GKS programme includes universities such as KAIST, POSTECH, Seoul National University, Yonsei University, Korea University, GIST, UNIST and many others.
Students can generally apply through either the Embassy Track or University Track, although the available universities, fields and application requirements vary by year and scholarship category.
2. Seoul National University Scholarships
Seoul National University offers several scholarships for international students.
For undergraduate applicants, the GKS programme can provide full tuition for eight semesters, a monthly living allowance, round-trip airfare and one year of Korean-language training.
Graduate students can also explore programmes such as the Graduate Scholarship for Foreign Students (GSFS), which can provide full tuition for up to four semesters and a monthly stipend. The SNU President Fellowship provides a more extensive package for eligible PhD applicants, including tuition, monthly living support, airfare, health insurance and Korean-language training.
SNU also offers the SNU Global Scholarship and Glo-Harmony Scholarship to eligible international graduate students.
3. POSTECH Scholarships
POSTECH is particularly interesting for students looking at STEM because of its focus on science and engineering.
For its international undergraduate admissions, POSTECH states that all admitted international undergraduate students receive a full tuition waiver, subject to the conditions for continued support. International students may also receive additional financial support, including a KRW 500,000 monthly living allowance, an arrival scholarship covering eligible travel expenses and a Korean proficiency scholarship.
POSTECH also participates in GKS for eligible graduate students.
4. KAIST Scholarships
KAIST is another institution international STEM students should investigate. It is particularly well known for programmes in fields such as engineering, computer science, artificial intelligence and the natural sciences.
International students should check the current KAIST admissions and scholarship information for their intended degree, as eligibility and funding packages can differ between undergraduate and graduate programmes.
5. University-Based Scholarships
You do not necessarily have to win GKS to study in South Korea on a scholarship.
Many Korean universities provide scholarships directly to international students, often based on academic performance, admission results, language proficiency or departmental recommendations. According to the Korean government’s Study in Korea platform, university scholarships for international students can range from partial tuition reductions to 100% tuition coverage, with some programmes also offering dormitory or other financial support.
This means students should not restrict their search to scholarships labelled “fully funded.” A university offering an 80–100% tuition scholarship could significantly reduce the total cost of studying in Korea.
South Korea offers international students far more than the opportunity to earn a degree abroad. With its strong reputation in technology, engineering, scientific research and innovation, the country provides an interesting environment for students looking to build careers in STEM.
From Computer Science and Artificial Intelligence to Mechanical Engineering, Biotechnology, Materials Science and Physics, there are several fields to consider depending on your interests and career plans. However, choosing a course should not be based on the popularity of a field alone. You should also consider the university, programme curriculum, language of instruction, admission requirements, career opportunities and available financial support.
If the cost of studying abroad is a concern, do not overlook scholarship opportunities. The Global Korea Scholarship (GKS) and university-specific scholarships can provide significant financial support for eligible international students.
Ultimately, the best STEM course for you is one that aligns with your interests, academic strengths and long-term career goals. Take time to compare your options, check the latest requirements directly with your preferred universities, and explore available scholarships before submitting your application.
