A: Most of our positions may be applied for with a single application, found here: https://www.princeton.edu/acad-positions/position/31924. You should indicate in that application which positions you are interested in.
However, the following department positions must be applied to individually:

  • Future Faculty in the Physical Sciences Fellowship
  • Visiting Fellow in the Space Physics group
  • Researcher Space Physics
  • Researcher in Hidden Symmetries and Fusion Energy

For the positions of interest, please see the individual ads for application information.

Q: I don't see the Russell Fellowship or the Carnegie-Princeton Fellowship listed here. Are they available?
A:
Unfortunately, we are not advertising these positions this year.  We hope to do so in future years, however.  

Q: How long should my research statement be?
A: For all of our positions, we will accept the AAS Postdoctoral Application Guidelines (see https://jobregister.aas.org/postdoc-application-guidelines). For other positions, please see the individual ads for guidance.

Q: Can I list Princeton as a host institution for the external fellowship for which I am applying?
A: Princeton University is an eligible host institution for national fellowships such as the NASA Hubble Postdoctoral Fellowship and the NSF AAPF. Candidates should contact the proposed faculty sponsor.

Princeton is also one of a select group of institutions eligible to host both the Brinson Prize Fellowship sponsored by STScI and the 51 Pegasi b Fellowship in Planetary Astronomy sponsored by the Heising-Simons Foundation. Princeton is home to a vibrant research program, including theoreticians, observers, and instrument builders, as well as links to major international projects such as the Transiting Exoplanet Survey Satellite, the HATNet, the HATSouth global network of telescopes, the HATPI all-sky survey, and the Terra Hunting Experiment. Postdoctoral candidates who may be interested in designating Princeton as a host institution for the 51 Peg Fellowship are encouraged to contact Professor Josh Winn in advance, to explore possible projects and connections to existing efforts.

Q: When are recommendation letters due?
A:
Recommendation letters are due about a week after you submit your application. No application will be discounted due to late letters, although it will delay our full and careful review of your application. Once you submit your application, you will have one day to make any changes on your own. At the conclusion of that one day, your references will receive an email, each with a unique url to upload their letter for you. The email will ask them to please upload their letter within one week.

Q: Who do I contact if I have more questions?
