Colorado State University

What you'll study

The programme combines advanced coursework, qualifying examinations, and sustained original research under the supervision of faculty active in nuclear and particle physics. Students typically take classes in both theoretical and experimental topics before concentrating on dissertation research.

• Core and advanced coursework — advanced quantum mechanics, quantum field theory, nuclear structure and reactions, particle physics and the Standard Model, statistical mechanics and thermal field theory.
• Specialist modules — detector physics and instrumentation, radiation interaction and dosimetry, experimental methods in nuclear physics, computational physics and numerical methods, data analysis and statistics for high-energy experiments.
• Research training — proposal development, research seminar series, topical graduate seminars in subfields (for example neutrino physics, heavy-ion collisions, hadron structure), and training in scientific communication.
• Laboratory and collaboration experience — opportunities to work on experimental projects using on-campus facilities and to participate in collaborations with national and international accelerator centres and national laboratories, or to pursue theoretical/computational projects using departmental HPC resources.
• Qualifying examinations and dissertation — after completing required coursework students pass qualifying/doctoral candidacy assessments and then focus on an original research programme leading to a written dissertation and oral defence.

Entry requirements

Applicants are normally expected to hold a master’s degree in physics or an equivalent degree with substantial coursework in core physics subjects. Strong preparation in quantum mechanics, electromagnetism, classical mechanics and mathematical methods for physicists is essential. Typical application components include:

• Academic transcripts demonstrating solid performance in undergraduate and, if applicable, postgraduate physics courses.
• A statement of research interests describing prior research experience and proposed areas of study within nuclear and particle physics.
• Letters of recommendation from academic or professional referees familiar with the applicant’s research potential.
• Evidence of quantitative and programming skills (for example in Python, C++ or MATLAB) is advantageous for many projects.
• International applicants must meet the university’s English language requirements.

Admission is competitive and based on the applicant’s academic record, research potential and fit with faculty expertise. Prospective students are encouraged to contact faculty members whose research aligns with their interests before applying.

Career prospects

Graduates from the programme go on to a wide range of careers that draw on deep technical knowledge, advanced computational skills and experience in experimental design and data analysis. Common pathways include:

• Academic research and teaching positions in universities and colleges, continuing with postdoctoral research in nuclear and particle physics or related fields.
• Research positions at national laboratories and large-scale experimental facilities, including roles in accelerator science, detector development and large collaborative experiments.
• Industry roles in sectors that value high-level quantitative and experimental skills, such as medical physics and imaging, radiation instrumentation, semiconductor and aerospace industries.
• Data-intensive careers in finance, technology and data science where advanced statistical and computational experience is transferable.
• Scientific policy, technical consulting, and roles in government agencies that require expertise in radiation safety, nuclear technologies or broader physical-science knowledge.
