Prospective Students

Prospective applicants will find all information about the AOS graduate program on the web site of the Graduate School of Princeton University. We recommend that you study the research interests of the AOS faculty and that you contact potential advisers when preparing the application. However, admission is generally not coupled to specific advisers or projects, and most students choose an adviser over the course of the first year. On average, about four students start our program each year, and many of our alumni pursue careers in science and academia. Please pay special attention to your Statement of Academic Purpose on your application as it helps us determine whether our Program is a good fit for you.

For convenience, we have compiled a checklist for your application; in all cases the information provided on the web site of the Princeton Graduate School is the authoritative source of information.
