Dartmouth College

What you'll study

The PhD programme combines advanced coursework, departmental seminars, substantial independent research and teaching experience. Students study core topics such as tectonics and structural geology, sedimentology and stratigraphy, igneous and metamorphic processes, geochemistry, geophysics and Earth system science, alongside methods courses in field techniques, petrology, geochronology, remote sensing and quantitative data analysis. Coursework is tailored to each student in consultation with their adviser, and typically includes graduate seminars and specialised classes drawn from related departments (for example engineering, environmental studies, and computer science).

Research lies at the heart of the degree. Students develop an original dissertation under the supervision of a faculty adviser, pursuing laboratory-based, field-based or computational projects. The programme emphasises hands-on training in modern laboratory methods and instrument-based analyses, rigorous quantitative skills, and frequent fieldwork—both on regional field trips in New England and in longer-duration field campaigns worldwide.

Programme milestones typically include completing required coursework and seminars, passing a qualifying or comprehensive examination, presenting and defending a dissertation prospectus, and writing and defending the doctoral dissertation. Teaching practice and participation in departmental colloquia and conferences are expected components of doctoral training.

Entry requirements

• Academic background: A strong undergraduate degree (or equivalent) in geology, Earth sciences, geophysics, geochemistry, environmental science or a closely related discipline. Many applicants also hold a relevant master's degree and/or substantial research experience.
• Research experience: Evidence of research potential demonstrated through previous research projects, honours theses, publications or significant laboratory/field experience is highly desirable.
• Application materials: Typically required items include academic transcripts, a statement of research interests outlining proposed areas of study and potential faculty mentors, a curriculum vitae, and academic references that can speak to research potential and academic preparation.
• English language: Non-native English speakers must demonstrate proficiency in English in line with Dartmouth's graduate admissions policy.
• Other considerations: Admissions decisions are based on the overall strength of the application and fit with faculty expertise and ongoing research projects. Prospective students are encouraged to contact potential advisers in advance to discuss research alignment.

Career prospects

Graduates of the PhD programme go on to a range of careers in academia, industry and the public sector. Common pathways include postdoctoral research and faculty positions at universities, research scientist roles at government agencies and national laboratories, and technical or leadership positions in environmental consulting, energy and natural resources companies. Alumni also work in geospatial and data science roles, environmental policy and planning, conservation organisations, and non-governmental organisations focused on climate and natural hazards.

The programme's emphasis on field methods, laboratory techniques and quantitative analysis prepares graduates for work that requires strong technical skills and independent research capability. Teaching experience gained during the PhD also supports careers in higher education.

Why study at Dartmouth College

Dartmouth offers a small, collegial Earth sciences department with close faculty–student mentorship and frequent opportunities for collaborative, interdisciplinary research across campus. The College's location provides ready access to diverse field sites in New England and to broader field campaigns, while on-campus facilities support modern laboratory and analytical work. Interactions with engineering, environmental studies and data science units expand methodological options for doctoral research.

Students benefit from a research-focused environment that combines rigorous training, active seminar programmes and support for conference travel and fieldwork. The department's culture of close supervision and collaborative projects is particularly well suited to students who seek personalised mentorship and the chance to develop a sustained, independent research programme.
