PhD in Applied Physics in Pasadena United States | California Institute of Technology

Applied Physics is an expansive discipline that bridges physics with various scientific and engineering domains. Caltech's Applied Physics program is inherently interdisciplinary, equipping students with advanced expertise across diverse physics and engineering areas. A key objective is to empower graduates with lifelong skills to leverage this knowledge, enabling them to pioneer technological and scientific advancements at knowledge frontiers. To earn a Ph.D. in Applied Physics, candidates must prove capable of designing and conducting original scientific research. This involves achieving mastery in a specialized area, acquiring problem-solving techniques applicable beyond one's specialization, cultivating rigorous scientific thinking for continuous self-education, and developing collaborative scholarly skills. Prospective students must first complete foundational coursework, then pass an oral qualifying exam presenting their research proposal and demonstrating subject mastery. After passing this examination, candidates collaborate with advisors to complete their dissertation. The Ph.D. is conferred upon faculty committee approval of the written dissertation and successful defense during a final oral examination. Note that Caltech does not offer a standalone master's degree in Applied Physics.
