John Hopkins University

What you'll study

The programme combines foundational coursework in mathematics and the physical sciences with discipline-specific classes in mineralogy, petrology, sedimentology, structural geology, geophysics and geochemistry. You will follow a curriculum of lectures and hands-on laboratory classes, and gain practical experience in field methods and data acquisition. Typical modules include:

• Introduction to Earth and Planetary Systems — broad overview of planetary processes, plate tectonics and Earth history.
• Mineralogy and Petrology — study of minerals and igneous, metamorphic and sedimentary rocks.
• Sedimentology and Stratigraphy — depositional processes, facies analysis and stratigraphic correlation.
• Structural Geology and Tectonics — deformation, faulting, folding and regional tectonic interpretation.
• Geophysics — fundamentals of seismic, gravity, magnetic and electrical methods for subsurface imaging.
• Geochemistry — chemical processes affecting minerals, fluids and rocks, isotope geochemistry.
• Palaeontology and Earth History — fossil record, evolutionary patterns and mass extinctions.
• Quantitative Methods and GIS — statistical analysis, numerical modelling and geographic information systems for spatial data.
• Field Methods — intensive field courses teaching mapping, sampling and observational techniques.
• Capstone Research or Senior Thesis — independent, faculty-supervised research project drawing on laboratory and field skills.

Students can usually choose between more technically oriented (BS) or broader liberal-arts (BA) pathways, permitting elective study in related fields such as environmental science, planetary science, engineering or applied mathematics.

Entry requirements

Applicants should demonstrate a strong academic record in secondary education with particular strength in mathematics and the natural sciences (biology, chemistry and physics). Typical preparation includes completion of advanced-level maths and at least two science subjects. Admissions assessors look for evidence of quantitative aptitude, laboratory experience or fieldwork where available, and a clear interest in Earth sciences.

Applications normally require academic transcripts, a personal statement describing academic interests and goals, and letters of recommendation from teachers or mentors. International applicants should provide the equivalent secondary qualifications and evidence of English language proficiency where required. Prospective students are encouraged to highlight any research experience, independent projects or extracurricular activities related to geology, environmental science or data analysis.

Career prospects

Graduates are prepared for a wide range of careers across the public, private and academic sectors. Common pathways include:

• Environmental and engineering consulting — site assessment, remediation and geotechnical investigations.
• Energy and resources — exploration and production roles in oil, gas and mineral industries, and jobs in renewable energy siting.
• Government and policy — positions with geological surveys, environmental protection agencies and natural hazard monitoring organisations.
• Research and academia — continued graduate study (MSc/PhD) in geology, geophysics, geochemistry or planetary science leading to research careers and teaching.
• Data science and GIS — roles using spatial analysis, remote sensing and large environmental datasets.
• Planetary science and space missions — applied skills for work on planetary geology and instrumentation development at research institutions and labs.

The programme’s emphasis on quantitative methods, field experience and mentored research also equips graduates for careers in science communication, risk analysis and environmental management.

Why study at Johns Hopkins University

Johns Hopkins is a research-intensive university with strong strengths in Earth and planetary sciences. Students benefit from access to active research groups, well-equipped laboratories and facilities for geochemical and geophysical analysis. Collaborative opportunities exist with nearby research centres and applied laboratories, enabling undergraduates to participate in faculty-led projects and internships.

Field training is an integral part of the curriculum, with organised field courses that teach practical mapping and sampling techniques. The university’s emphasis on cross-disciplinary work means students can combine Earth sciences with applied mathematics, engineering, environmental policy or data science. Dedicated career services and alumni networks support transitions into industry, government and graduate study.
