PhD in Applied Physics

The California Institute of Technology has a rich history of scientific and technological innovation and is globally acclaimed for its commitment to cutting-edge research. Caltech is known for its exceptional programs in science and engineering. The university offers a range of undergraduate, graduate, and doctoral programs, with an emphasis on STEM (science, technology, engineering, and mathematics) fields. What sets Caltech apart is its dedication to fostering a culture of scientific inquiry and innovation. With a faculty composed of leading scholars and a remarkable record of scientific achievement, including numerous Nobel Prizes and groundbreaking discoveries, Caltech remains at the forefront of scientific exploration and technological advancement. Its commitment to pushing the boundaries of knowledge makes it a top choice for students seeking an education deeply rooted in scientific discovery and innovation.

To receive the doctoral degree in Applied Physics students must demonstrate the ability to formulate and execute an original program of scientific study. As part of this, a doctoral candidate is expected to develop a deep understanding in a chosen field of specialization; to develop tools with which to assess problems outside one's field of specialization; to develop rigor and strength in the physical sciences for self-education beyond formal training; and to develop skills to become a productive member of the community of scholars. All students wishing to enter the program must complete a series of preparatory courses, followed by an oral candidacy exam in which the student describes their proposed topic of research and is examined on their knowledge of course subject matter. Upon passing the candidacy examination, students work towards completion of a thesis in consultation with their research adviser. The doctoral degree is awarded upon approval of a written thesis by a faculty committee, and successful defense of the thesis in a final oral examination. There is no separate master's program in applied physics. However, with the approval of the student's adviser and the applied physics option representative, the degree of Master of Science in Applied Physics may be awarded after the fulfillment of the course requirements described below.
