Co-supervised PhD


A thesis may be supervised by two professors or lecturers accredited to direct research. The disciplinary field of the co-supervisor is, in this case, significantly different from that of the supervisor. If the co-supervisor works in another institution, an agreement is signed.
Co-supervision is a way of pooling the expertise of two research units and of giving the PhD student the possibility of receiving material and financial support from both units.
Although a co-supervision agreement must be signed by the two supervisors concerned, only one administrative enrollment is required.
There is only one defense and it takes place at the university where the PhD student is enrolled.

Thesis advisors

Professors who have not yet obtained an accreditation to direct research may act as thesis advisors. The work is nevertheless placed under the responsibility of the supervisor, holder of the HDR (accreditation to direct research).

The thesis advisor may be a representative of the company in which the PhD student does part of his/her work.

The thesis advisor supervisory rate, as well as that of the co-supervisor, is defined at the time of enrollment, in consultation with the director of the research unit. It should be noted that the supervisor holding the HDR (accreditation to direct research) must have a minimum of 50% supervision rate.

The number of professors or researchers not accredited to direct research is limited to 3.



  1. The PhD student submits the project to his/her thesis supervisor and co-supervisor, who will complete the co-supervision agreement, using the model defined by the UGA (downloadable below),
  2. He/she will then get it signed in 4 original copies by the directors of the two laboratories and by the partner university,
  3. The agreement will then be sent to the administrative manager of the laboratory who will have it signed by the president of the UGA.
