Program Introduction

The graduate program in Physics at the California Institute of Technology (Caltech) provides cutting-edge research and education in the fundamental principles and applications of physics. The program offers opportunities to develop in-depth expertise in diverse areas including particle physics, quantum mechanics, condensed matter physics, astrophysics, and gravitational wave physics. The Caltech Physics graduate program is designated as a STEM (Science, Technology, Engineering, and Mathematics) field, allowing international students to benefit from up to 36 months of Optional Practical Training (OPT) after graduation. The Caltech Physics department maintains small student groups working with distinguished faculty, including Nobel laureates, creating a unique environment where students can collaborate directly with world-class researchers. The program emphasizes both theoretical and experimental physics, offering exceptional opportunities for students to conduct frontier research through collaborations with renowned facilities such as LIGO (Laser Interferometer Gravitational-Wave Observatory), JPL (Jet Propulsion Laboratory), and IQIM (Institute for Quantum Information and Matter). Through rigorous coursework and research mentorship, students develop into independent scientists prepared to take leading roles in academia, industry, and government laboratories.
