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.

If you would like to connect with a current AOS student or postdoc who can answer your questions about the AOS PhD program and application process, please fill out this form for the Applicant Mentorship Program.

Statement of Academic Purpose

In addition to following the requirements of the graduate school, this statement will be most useful to the AOS selection committee if it includes the following information: Why are you interested in atmospheric and oceanic science, and in our program in particular? Why are you interested in pursuing a PhD? What areas of atmospheric and oceanic science most interest you, and why? How do you envisage contributing to the atmospheric and oceanic sciences? Which of the AOS faculty would you be interested in working with, and why?
