Your PhD project

You are planning to apply for a PhD. Here is some information about your PhD application. You can also find information about the PhD, funding, post-thesis, etc. on this FAQ or on the CJC website (in French).

We remind you that it is essential to make contact and to meet the PhD advisor who proposes the PhD subject to which you wish to apply. You can also ask your potential supervisors to contact her/his former doctoral students or post-doctoral fellows to be able to discuss with them their PhD thesis progress, the interactions with your future advisor and your future laboratory environement. They can also answer questions about the thesis scientific topic.


The PhD applications must be submitted online, from February 3rd to April 23rd, 2020.

To apply for a PhD Project, go to the webpage describing the subject and click on the *Candidater* button located at the top left of the page. Other kind of applications (emails etc) will not be accepted. You will receive an acknowledgment of receipt from the Doctoral School. If you think you have correctly completed your file, but did not receive an acknowledgment of receipt, please contact the Doctoral School directly at

The application must contain the following documents:

  1. A complete curriculum vitae detailing your education, previous research experiences and their duration.
  2. A cover letter explaining your motivation for a thesis in astrophysics, and the expertise you have acquired to undertake this project
  3. A copy of all academic results since the first year of University/College, with all the grades.
  4. Between one and three letters of recommendation from persons other than the thesis director, sent directly to

These documents must imperatively be submitted by 15 April 2020. We will not accept documents after this date.

The potential PhD thesis supervisors need to validate the candidate applications via ADUM and applications that are not validated will not be considered. It is important to contact the potential PhD thesis supervisors before submitting to give them all the information needed before validation. A failure to contact them might result in a lack of validation, and in that case your application will not be considered.

If your application is selected for an interview, you must send to by the final selection date (the date will be at the beginning of July and will be posted as soon as we have it):

  1. A copy of the diploma giving access to the thesis (Master) or an attestation indicating the date of the corresponding jury,
  2. The Master’s thesis manuscript,

must reach the ED before the final jury by email

Double application

It is suggested to apply on two different subjects (classified A and B), in laboratories belonging to different institutions, in order to leave some flexibility to the jury in awarding contracts. However, do not apply to more than two subjects!
