Thesis

2021 Thesis proposals

Each year, IRSN offers new topics for doctoral research, defined in close collaboration with the academic world.

A majority of students have a doctoral contract funded or co-funded by the Institute. The other students benefit from external funding

Eligibility requirements

To be eligible for thesis funding, you must hold a Master's degree or an equivalent diploma allowing you to apply for a doctoral degree, before October of the current year.

In cases of diploma equivalence, the authorization to apply to the doctoral school must be verified before preparing the application form.

Applicants must be under 26 years of age. Exceptionally, this limit may be waived.

Thesis selection process

To apply you must contact the thesis tutor by email, sending him a resume and a cover letter. If your profile attracts his attention, he will inform you on the steps to take for the rest of your application.

We draw your attention to the fact that the thesis proposals posted are still subject to validation by the IRSN Thesis Commission. A limited number of thesis offers may be removed by early March.

Financing

The amount of the doctoral contract allocated by IRSN is around €2040 gross monthly during the first two years and €2090 gross monthly in the third year.

For some proposed thesis related to external financing, this amount may be different.
