Earth and Planetary Sciences

The Department of Earth and Planetary Sciences (EPS) investigates the materials, processes, and history of Earth and other planetary bodies. Spanning the 4.56-billion-year history of our solar system, EPS research and education examine the chemical and physical properties of minerals, rocks, soils, and water; the processes that shape planetary interiors and surfaces; and the co-evolution of life and the environment. The department’s work balances fundamental scientific discovery with practical applications that are critical to securing a sustainable future for human society.

Academic Programs

EPS offers diverse academic pathways opens in a new tab designed to prepare students for leadership roles in academia, environmental consulting, resource management, and public policy:

• Undergraduate Programs: Leading to a Bachelor of Science (B.S.) in Earth and Planetary Sciences, with opportunities for specialized concentrations, independent research, and extensive field-based learning.

• Coterminal Programs: Allowing qualified Stanford undergraduates to simultaneously earn a B.S. and a Master of Science (M.S.) degree.

• Graduate Programs: Offering advanced research-focused curricula leading to Master of Science (M.S.) and Doctor of Philosophy (Ph.D.) degrees.

Research Areas and Societal Impact

Research within the department is highly interdisciplinary, bridging physics, chemistry, biology, and computational sciences. Key areas of investigation and their real-world applications include:

• Earth History and Biogeochemistry: Examining stratigraphic, paleobiological, and geochemical records to reconstruct ancient oceans, atmospheres, and climates, providing vital context for modern climate change.

• Natural Hazards and Environmental Engineering: Assessing and remediating geological hazards—including earthquakes, volcanic eruptions, landslides, and floods—while improving soil and water quality.

• Resource Management and Sustainability: Evaluating the origin, extraction, and stewardship of critical energy, mineral, and groundwater resources.

• Planetary Exploration: Utilizing remote sensing, laboratory experiments, and robotic mission data to study the formation, surfaces, and habitability of other planets.
