PhD in Planetary Science - Planetary Formation in Pasadena United States | California Institute of Technology

Caltech ranks among the world's premier institutions for planetary science research. Our program 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 these research initiatives. The department includes astronomers observing solar system objects and exoplanets, mission specialists working on current and future spacecraft projects, researchers investigating Martian geology and atmospheric processes, and scholars studying virtually every significant area of planetary science. To earn a Ph.D. in planetary science, students must complete Ge 101 and 102, along with specialized courses in planetary formation/dynamics (Ge/Ay 133), atmospheres (Ge/ESE 150), interiors (Ge 131), and surfaces (Ge 151). The program also requires 45 units of advanced coursework in a chosen specialization, which can be fulfilled through a subject minor or an advisor-approved course plan. All candidates should demonstrate physics and mathematics proficiency equivalent to Ge 108, with advanced coursework strongly recommended. Students must regularly attend planetary sciences seminars and complete six terms of Ge 109 (oral communication), typically during their first two years, including at least one 30-minute research presentation. Most students present their ongoing work annually after their first year.
