We seek excellent, motivated students from a variety of backgrounds. An undergraduate degree and/or professional experience in the earth or planetary sciences is beneficial, but it is not a requirement for graduate admission to our department. We encourage applications from interested students with undergraduate degrees in any of the physical and biological sciences, mathematics, and engineering.

If you would like to join our department as a graduate student, please follow these steps to apply for admission. The deadline for fall admission is December 1. If the application fee presents a barrier to applying, please email Shelby Russell at for a fee waiver.

We recognize that it can be financially burdensome to relocate to a new city to attend a Ph.D. program. Students who are accepted to Ph.D. programs at JHU can apply to receive a $1500 need-based grant to offset the costs of relocating to JHU.

These grants provide funding to a portion of incoming students who, without this money, may otherwise not be able to afford to relocate to JHU for their Ph.D. program.

This is not a merit-based grant. Applications will be evaluated solely based on financial need. Click here for more information:
