What you'll study

The PhD programme combines advanced coursework, oral and written qualifying examinations, and an original research dissertation. In the initial years students take a flexible set of advanced modules that build depth in a chosen specialism while maintaining breadth across Earth-science disciplines. Typical areas of study include:

• Advanced Petrology and Mineralogy — igneous and metamorphic processes, phase equilibria and microstructural analysis.
• Sedimentology and Stratigraphy — depositional systems, sequence stratigraphy and basin-fill evolution.
• Structural Geology and Tectonics — kinematics and mechanics of deformation, mountain building and fault-related processes.
• Geochemistry and Isotope Geochemistry — trace element geochemistry, radiogenic and stable isotopes for Earth-system processes.
• Geophysics and Seismic Interpretation — applied seismic methods, potential fields, and subsurface imaging.
• Hydrogeology and Environmental Geoscience — groundwater systems, contaminant transport and applied remediation.
• Analytical and Computational Methods — electron microscopy, X-ray diffraction, mass spectrometry, GIS, numerical modelling and data analysis.
• Field Methods and Field-based Research — mapping, stratigraphic logging, sampling and regional field campaigns in nearby basins.

Students work under the supervision of a faculty advisor to develop an independent research project. The programme emphasises hands-on analytical skills in SMU's laboratories, experience with field campaigns in regional geological provinces, and dissemination of results through peer-reviewed publication and conferences.

Entry requirements

Applicants normally hold a relevant master's degree (or a strong bachelor’s degree with significant research experience) in geology, earth sciences, geophysics, geochemistry or a closely allied discipline. Expected qualifications and application components typically include:

• Academic transcripts demonstrating a strong record in core undergraduate and graduate coursework (petrology, sedimentology, structural geology, geophysics, chemistry and mathematics where applicable).
• A statement of research interests outlining proposed doctoral research directions and alignment with SMU faculty expertise.
• Curriculum vitae highlighting research experience, publications or technical skills.
• Two to three academic references from supervisors or faculty who can assess research potential.
• For international applicants, proof of English language proficiency through recognised tests unless exempt.

Some applicants may be invited to interview with potential supervisors. The programme seeks candidates with demonstrated independence, quantitative skills, and the ability to carry out field and laboratory research.

Career prospects

Graduates with a PhD in Geological and Earth Sciences from SMU pursue a wide range of careers. Common pathways include:

• Academic careers as postdoctoral researchers and faculty in universities and research institutes.
• Industry positions in energy companies (exploration and production, geological modelling and reservoir characterisation), mineral and mining companies, and geothermal energy firms.
• Environmental and engineering consultancies focusing on site characterisation, remediation, hydrogeology and geotechnical assessment.
• Government and public-sector roles in geological surveys, regulatory agencies and natural-hazard assessment.
• Specialist technical roles in laboratories, data science and remote sensing groups that apply Earth-science expertise to resource management and environmental monitoring.

The programme prepares graduates to lead research projects, contribute to interdisciplinary teams, and translate geoscientific results into practical applications for industry and policy.

Why study at Southern Methodist University

SMU's Department of Earth Sciences offers a research-intensive environment with relatively small cohorts and close faculty supervision. The department's location provides easy access to key regional field areas and active energy-industry partners, supporting applied research in basin analysis, petroleum systems and environmental geology. Students benefit from modern analytical facilities and instrumentation, opportunities for interdisciplinary collaboration across campus, and established links with government and industry that help with field logistics, internships and knowledge transfer.

Faculty research strengths span petrology, stratigraphy, structural geology, geochemistry and geophysics, enabling students to pursue diverse projects and to receive mentorship from recognised specialists. The department emphasises professional development through teaching opportunities, conference participation and training in modern laboratory and computational techniques, preparing graduates for leadership roles in academia, industry and government.
