University of San Diego

What you'll study

The programme combines advanced coursework, research training and a sustained dissertation project. Core topics typically include classical and quantum mechanics, statistical mechanics, electrodynamics, and advanced laboratory techniques, while students also take modules in computational physics, materials science, spectroscopy and experimental methods depending on their focus.

• Coursework and seminars: Advanced topical courses to build theoretical and technical breadth, plus regular research seminars and journal clubs.
• Research rotations and specialisation: Early-stage rotations or collaborative projects help students identify a dissertation advisor and research direction in areas such as condensed matter, photonics and optics, computational modelling, or interdisciplinary applications.
• Research methods and professional training: Training in experimental design, data analysis, scientific computing, and responsible conduct of research. Opportunities for pedagogical training and supervised teaching are commonly available.
• Qualifying assessment and candidacy: After completing required coursework, students typically pass a qualifying examination or research proposal to advance to doctoral candidacy.
• Doctoral dissertation: The major component of the degree is an original research project carried out under faculty supervision, culminating in a written dissertation and public defence.

Entry requirements

Applicants should hold a strong undergraduate degree in physics, applied physics, engineering, mathematics or a closely related scientific discipline; many successful applicants also hold a master’s degree. A competitive application normally demonstrates substantial preparation in advanced mathematics and physics, plus evidence of research potential.

• Academic transcripts showing relevant coursework (calculus, differential equations, linear algebra, classical and modern physics courses).
• A CV outlining research experience, publications or project work where applicable.
• A personal statement describing research interests and fit with potential faculty supervisors.
• Two or three letters of recommendation from academic or professional referees who can speak to research preparedness and potential.
• International applicants should demonstrate English language proficiency according to university policy.

Specific admissions requirements and any departmental expectations (such as recommended prerequisite courses or preferred evidence of laboratory or computational experience) are available from the University of San Diego graduate admissions and the programme’s graduate coordinator.

Career prospects

Graduates of a PhD in Physical Sciences move into a wide range of careers where advanced analytical, technical and research skills are valued. Typical destinations include:

• Academic positions and postdoctoral research in physics and related fields.
• Research and development roles in industry sectors such as photonics, materials, semiconductors, aerospace and defence.
• National and government laboratories conducting fundamental and applied science.
• Data science, quantitative analytics and modelling roles in finance, technology and consultancy.
• Science policy, technical management, and higher education teaching positions.

The programme emphasises transferable skills—experimental design, numerical simulation, scientific communication and project management—that support careers both inside and outside traditional research environments.
