University of Dayton

What you'll study

The PhD programme combines advanced coursework, qualifying examinations and an extended original research dissertation. Coursework provides deep grounding in foundational and specialised topics while research projects advance new knowledge in areas such as solid mechanics, materials and manufacturing, thermal and fluid sciences, dynamics and controls, computational mechanics, and biomedical/mechatronic systems.

• Core and advanced modules — typical subjects include continuum mechanics, advanced dynamics and vibrations, finite element methods and computational mechanics, advanced thermodynamics and heat transfer, fluid dynamics, control theory and systems, materials science and microstructure, and experimental methods.
• Research seminars and methods — regular seminars on research techniques, ethics, statistical methods for engineering research, and preparation of proposals and technical manuscripts.
• Specialist electives — students choose electives aligned with their research focus such as composites and additive manufacturing, micro/nano mechanics, multi-physics simulation, energy conversion systems, biomechanics, and sensors and instrumentation.
• Qualifying assessment and proposal — after completing core coursework, students undertake a qualifying examination and prepare a dissertation proposal that defines the scope and methodology of the doctoral research.
• Doctoral dissertation — original, supervised research culminating in a written thesis and an oral defence. Research is often collaborative with industry or government laboratories and may include experimental, computational or theoretical work.

Entry requirements

Applicants are normally expected to hold a relevant master’s degree in mechanical engineering or a closely related engineering or science discipline. Exceptionally qualified candidates with a strong bachelor’s degree and research experience may also be considered. Admissions emphasise prior academic performance, research potential and alignment with faculty expertise.

• Official academic transcripts demonstrating a strong record in engineering, mathematics and science courses.
• A detailed CV or résumé outlining technical experience and any research or publications.
• A statement of research interests describing proposed areas of study and potential faculty supervisors.
• Letters of recommendation from academic or professional referees who can attest to research ability and preparedness for doctoral study.
• Proof of English language proficiency for applicants whose first language is not English, in line with university requirements.
• Funding support, such as consideration for teaching or research assistantships, may be discussed during the application; applicants should indicate funding needs in their materials.

Career prospects

Graduates of the PhD in Mechanical Engineering enter roles that require deep technical expertise and independent research capability. Typical career paths include academic positions (postdoctoral appointments and faculty roles), R&D and technical leadership in aerospace, automotive, energy, materials and manufacturing industries, positions in national laboratories and government research organisations, and senior roles in product development and innovation.

Doctoral training also prepares graduates for roles in computational modelling, experimental test and measurement, design of advanced materials and systems, consultancy, and technology entrepreneurship where they can translate research into commercially viable products and processes.
