University of San Diego

What you'll study

Although University of San Diego does not offer a PhD in Aerospace, Aeronautical, and Astronautical Engineering, a typical PhD in this field at research universities focuses on advanced topics such as fluid dynamics, aerodynamics, propulsion systems, aircraft and spacecraft structures, guidance and control, avionics, computational fluid dynamics (CFD), hypersonics, materials for extreme environments, and multidisciplinary design optimisation. Core coursework commonly covers advanced mathematics for engineers (including applied PDEs and numerical methods), experimental methods, and specialised seminars in propulsion, structural dynamics, and control theory. The doctoral phase centres on an original, publishable research dissertation supervised by faculty, with students undertaking qualifying exams, research rotations or preliminary proposals, and contributing to peer-reviewed conferences and journals.

Entry requirements

For PhD programmes in aerospace engineering at research universities, typical entry expectations include:

• A relevant master’s degree or a strong bachelor’s degree in aerospace, mechanical engineering, physics or a closely related field.
• Demonstrated research potential through a master’s thesis, undergraduate research projects, publications, or industry R&D experience.
• Solid foundation in mathematics and core engineering subjects (fluid mechanics, thermodynamics, dynamics and control, materials/structures).
• Academic transcripts and letters of recommendation from academic or research supervisors.
• A statement of research interests that aligns with faculty expertise and available research groups.
• International applicants typically need to demonstrate English language proficiency where applicable.

Career prospects

Graduates with a PhD in aerospace-related fields pursue careers across academia, government laboratories and industry. Typical paths include university faculty and postdoctoral research positions, research scientist or principal engineer roles in aerospace and defence companies, systems and propulsion specialists, computational modelling and simulation experts, and technical leadership positions in space agencies and national labs. Doctoral training also opens opportunities in adjacent sectors such as autonomous systems, advanced manufacturing, energy systems, and high-tech consulting where deep analytical, modelling and experimental skills are valued.

Why study at University of San Diego

While USD does not award a PhD in aerospace engineering, the university provides strengths that support students preparing for doctoral study or technology careers in aerospace-related areas. USD’s engineering school emphasises hands-on learning, interdisciplinary collaboration, and small cohort sizes that allow close mentorship from faculty. Students benefit from proximity to a strong regional aerospace and defence industry cluster in Southern California, internship and project opportunities with local companies, and collaborations with nearby research institutions.

Prospective doctoral candidates can use USD undergraduate and masters-level programmes to build the technical foundation and research portfolio required for competitive PhD applications elsewhere. USD’s career services, industry connections, and experiential learning projects are practical assets for students aiming to move into research-intensive programmes or technical roles in the aerospace sector.
