I am interested in the formation and evolution of the Solar System bodies and the ways we can constrain planetary interiors by geophysical measurements. If these topics interest you, I encourage you to apply to the Stanford AeroAstro Ph.D. program. A bit more info can be found here. The graduate school admission process at Stanford AeroAstro is not in the hands of individual faculty. It is managed collegially by the department. I encourage applicants to review the admission policies here. I also encourage you to apply for external funding. Here is a list of possible funding sources. If you interested in post-doc, you could explore this opportunity.
