PhD in Planetary Science - Missions and Instrumentation in Pasadena United States | California Institute of Technology

Caltech ranks among the world's premier institutions for planetary science research. Our expertise spans nearly every aspect of the field, supported not only by dedicated planetary science faculty and students but also through collaborations with other Caltech divisions including astronomy, geology, geochemistry, and environmental science and engineering. Our partnership with nearby JPL further strengthens our research capabilities. Our community includes astronomers observing solar system objects and exoplanets, mission specialists working on current and future spacecraft projects, researchers analyzing Martian geology and atmospheric processes, and scholars investigating virtually every significant topic in planetary science. To earn a Ph.D. in planetary science, students must complete Ge 101 and 102, along with specialized courses in planetary formation (Ge/Ay 133), atmospheres (Ge/ESE 150), interiors (Ge 131), and surfaces (Ge 151). The program also requires 45 advanced units in a focused specialization area, which can be fulfilled through a subject minor or a customized course plan approved by faculty advisors. Students should demonstrate physics and mathematics proficiency equivalent to Ge 108, with advanced coursework strongly recommended. This prerequisite may be satisfied through prior studies or by completing the designated class. All candidates must regularly attend planetary sciences seminars and complete six terms of Ge 109 (oral communication), typically during their first two years, including delivering at least one 30-minute seminar presentation. Most students present their research annually after their first year.
