Colorado State University

What you'll study

The PhD programme combines advanced coursework, qualifying examinations, and an original research dissertation. Early in the programme you take graduate-level courses to build depth in core mechanical engineering subjects and to support your research specialism; typical course topics include advanced continuum mechanics, computational methods in engineering, experimental methods, heat transfer and fluid mechanics, dynamics and control, materials and manufacturing, and applied optimisation.

Research areas within the department commonly include (but are not limited to):

• Thermal and fluid sciences (turbulence, multiphase flow, heat transfer, energy systems)
• Solid mechanics, fracture and materials science, including additive manufacturing and composites
• Dynamics, controls and robotics, including autonomous systems and mechatronics
• Biomechanical engineering and biomedical devices
• Micro- and nanotechnology, sensors and MEMS
• Advanced manufacturing and materials processing

Students typically complete a combination of core and elective graduate courses, pass a written and/or oral qualifying examination, propose and defend a dissertation research plan, and then conduct original research under the supervision of a faculty advisor, culminating in a written dissertation and oral defence. Interdisciplinary collaboration is encouraged; many students work with colleagues in materials science, electrical engineering, biomedical engineering, and energy centres.

Entry requirements

Applicants are normally expected to hold a strong bachelor’s degree in mechanical engineering or a closely related field; applicants with a master's degree may be prioritised for direct research admission. Successful candidates demonstrate strong preparation in mathematics, mechanics, thermofluids, and numerical methods. Typical application components include academic transcripts, a statement of research interests outlining potential faculty matches and proposed research directions, at least two academic or professional letters of recommendation, and a CV.

International applicants must demonstrate English language proficiency according to the university’s requirements. Admission decisions consider the overall profile of the candidate, including prior research experience, publications or project work, fit with faculty research, and availability of faculty mentorship and funding. Prospective students are encouraged to contact potential supervisors before applying to discuss research alignment.

Career prospects

Graduates with a PhD in Mechanical Engineering pursue careers across academia, government research laboratories, and industry. Common roles include university faculty, postdoctoral researcher, principal engineer or research scientist in aerospace, automotive, energy, robotics, manufacturing and biomedical device companies, and technical leadership positions in start-ups. PhD holders may also work in national laboratories and in advanced R&D groups focused on next‑generation materials, renewable energy systems, autonomous systems, and complex modelling and simulation challenges. The programme’s emphasis on original research, technical communication and grant-writing prepares graduates for leadership roles where they design experiments, lead teams and translate research into applications.
