Caltech’s Division of Geological and Planetary Sciences (GPS) offers graduate study in geobiology, focusing on how life interacts with the Earth over geological timescales. The curriculum integrates geological and genetic evidence to explore the impact of life on Earth and vice versa, using fieldwork, laboratory analysis, and interdisciplinary research. The program prepares students for research careers in academia, government, or industry, leveraging advanced laboratories in molecular geobiology and close ties to facilities such as NASA's Jet Propulsion Laboratory. Caltech's graduate programs in this division are highly flexible and interdisciplinary, allowing students to craft individualized research pathways within GPS and across divisions. 来源： https://catalog.caltech.edu/current/areas-of-study-and-research/geological-and-planetary-sciences/
