The PhD subjects still available for PhDs starting in the Fall 2015 are the following:
PhDs usually start in October. They must be completed in three years at full time.
To apply, first choose a thesis topic which you find interesting. Then contact the supervisor, to check whether the thesis is still "open". Send her/him a CV. Once you obtain the consent of the supervisor, then submit an application for funding. Once funding is obtained, there remains only paperwork: enrollment in the Ecole Doctorale, the University, with the CEA, etc.
Several organizations offer funding. Each one has its own rules and timetable.
CFR: CEA PhD Fellowship.
The CFR funding is specific to CEA. The student receives 2040 euros "brut" per month, for 3 years. Usually, the contract starts on 1st October.
For CFR, the deadline for applications is late April. The application must be performed electronically by the PhD supervisor or by S.Nonnenmacher. Decisions are taken by the head of CEA. The only selection criterion is academic excellence. Responses are expected around mid-June. More information may be found at www-instn.cea.fr.
PhD contract from Universities. These contracts are awarded by the "doctoral schools". See www.etudiant.gouv.fr, or ED 107. The deadline for application is towards the end of May. The selection will be done in two steps: a preselection leads to a short list of applicants, which will be interviewed by a selection panel.
Certain PhD advisors benefit from grants (from the French ANR, the ERC, some European network) allowing to fund PhD theses.
Please contact Stéphane Nonnenmacher for more information.
