PhD in Department of Physics

The Department of Physics at Pohang University of Science and Technology (POSTECH), located in Nam-gu, South Korea, offers a doctoral program taught in English for students conducting independent research into the fundamental behavior of matter and energy. Depending on the laboratory a student joins, doctoral research can focus on condensed matter physics, particle and nuclear physics, optics and photonics, quantum information, or astrophysics, typically combining theoretical modeling with experimental or computational work. Candidates are trained to formulate research questions, design experiments or simulations, and interpret results in a way that contributes new understanding to the field, culminating in a dissertation defended before faculty. Because physics research often depends on specialized equipment and computing resources, students typically spend substantial time in laboratory or computational facilities alongside coursework that strengthens their theoretical foundation. The coursework phase of the program runs two years, with entry offered in the middle of February or the beginning of September, giving international applicants flexibility in scheduling their transition into doctoral study. Graduates of a physics doctoral program commonly move into research careers at universities, national laboratories, or technology companies working on semiconductors, photonics, or materials science, while others pursue university teaching positions. POSTECH has a research profile closely tied to South Korea's electronics and materials industries, and its campus in Nam-gu is organized around applied and fundamental science research conducted alongside major national research facilities. This setting gives doctoral physics students access to instrumentation and collaborators that support both fundamental and applied work over the course of their studies.
