Apply for Scholarship

The French National Centre for Scientific Research (CNRS) is Europe’s largest public research organization, operating under the French Ministry of Higher Education and Research. For international students pursuing a PhD in agricultural sciences, CNRS offers a multidisciplinary environment spanning biology, ecology, and environmental sciences. Doctoral candidates are affiliated with CNRS laboratories and enrolled in doctoral schools across France, often in partnership with universities. Research areas include plant biology, agroecology, soil science, and sustainable agriculture. The PhD typically lasts three years, with funding provided through doctoral contracts. International applicants must secure a supervisor and funding before applying, and the process involves direct contact with research units. CNRS emphasizes international collaboration, with numerous joint laboratories and programs. The official website provides a directory of research units and open PhD positions, serving as the primary resource for prospective students.

Fields of Study in Agricultural Sciences

CNRS laboratories conduct research across a wide spectrum of agricultural and environmental topics. PhD projects are often interdisciplinary, combining biology, ecology, and social sciences. Below are some of the main fields where international students can find opportunities.

Plant Biology and Physiology

Research on plant growth, development, and responses to environmental stresses. Laboratories like the Institute of Plant Sciences Paris-Saclay (IPS2) investigate molecular mechanisms, genomics, and epigenetics to improve crop resilience and productivity.

Agroecology and Sustainable Agriculture

Studies on ecological interactions in agricultural systems, including biodiversity, pest management, and soil health. The Center for Functional and Evolutionary Ecology (CEFE) in Montpellier leads projects on ecosystem services and sustainable farming practices.

Soil Science and Biogeochemistry

Research on soil formation, organic matter dynamics, and nutrient cycling. The Institute of Ecology and Environmental Sciences (IEES) in Paris examines soil microbial communities and their roles in carbon sequestration and plant nutrition.

Environmental Microbiology

Investigation of microorganisms in agricultural and natural environments, focusing on plant-microbe interactions, bioremediation, and microbial ecology. The Laboratory of Environmental Biotechnology (LBE) at Narbonne works on anaerobic digestion and bioenergy.

Plant Breeding

Although CNRS primarily conducts fundamental research, some units collaborate with INRAE on plant breeding programs. For instance, the Genetics, Diversity and Ecophysiology of Cereals (GDEC) laboratory in Clermont-Ferrand studies wheat genetics and participates in breeding for disease resistance and yield improvement.

These fields represent just a sample of the agricultural research conducted within CNRS. Prospective students are encouraged to explore the CNRS laboratory directory to find specific projects and supervisors. Each laboratory has its own research priorities and funding sources, so direct contact is essential.

Eligibility Criteria for PhD Candidates

Admission to a CNRS PhD program is highly competitive and requires a strong academic background. While specific criteria vary by laboratory and doctoral school, the following general requirements apply to most international applicants.

Academic Qualifications

Applicants must hold a Master's degree (or equivalent) in a relevant field such as biology, ecology, agronomy, or environmental science. A strong academic record and research experience, such as a Master's thesis, are essential. Some doctoral schools may require a minimum grade point average.

Supervisor Agreement

Before applying, candidates must secure a supervisor who is a CNRS researcher or affiliated with a CNRS laboratory. The supervisor must agree to mentor the PhD project and provide a research plan. This is typically done through direct email contact or by applying to advertised PhD positions.

Funding

Applicants must have confirmed funding for the entire duration of the PhD (usually 36 months). Funding can come from a doctoral contract (e.g., CNRS, Ministry of Higher Education), a research project grant, or an external fellowship (e.g., from a home country government or international organization). Without funding, admission is not possible.

Language Proficiency

While French is the working language in many laboratories, English is widely used in research. Some doctoral schools may require proof of English proficiency (e.g., TOEFL or IELTS) if the thesis will be written in English. However, this is not a uniform requirement and depends on the specific doctoral school's rules.

Visa and Administrative Requirements

Non-EU/EEA students must obtain a long-stay student visa (VLS-TS) for France. This process requires proof of admission, funding, and accommodation. CNRS provides support for international researchers through its International Mobility Office, which assists with visa procedures and administrative formalities.

Doctoral Contract Salary

PhD students funded by a CNRS doctoral contract receive a monthly gross salary of approximately €2,300 (as of 2025). This amount is set by the French government and may vary slightly depending on the doctoral school and additional responsibilities. The contract includes social security coverage and pension contributions.

Research and Training Budget

In addition to the salary, doctoral students often have access to a research budget provided by their laboratory or research project. This can cover consumables, equipment, travel to conferences, and training courses. The amount varies widely, typically ranging from €2,000 to €5,000 per year, depending on the project's funding.

Application Process for International PhD Candidates

The application process for a CNRS PhD is decentralized and differs from many other institutions. There is no central application portal; instead, candidates must apply directly to a laboratory and supervisor. The following steps outline the typical pathway.

Identify a Research Unit and Supervisor: Browse the CNRS laboratory directory and research group websites to find a topic that matches your interests. Look for recent publications and ongoing projects. Shortlist potential supervisors and reach out via email with your CV, academic records, and a brief statement of interest. Be prepared to discuss your background and motivation.
Secure Funding: Funding is mandatory. If you do not have a scholarship, you can apply for a CNRS doctoral contract when a position is advertised on the CNRS jobs portal or via the doctoral school's website. Alternatively, you can apply for external fellowships such as the Eiffel Scholarship, the Erasmus Mundus Joint Doctorate, or funding from your home country. Your supervisor can also help identify funding opportunities.
Submit Your Application to the Doctoral School: Once you have a supervisor and funding, you must be registered at a doctoral school associated with the laboratory. The doctoral school's website will provide the specific application requirements, which typically include a research proposal, academic transcripts, recommendation letters, and a language proficiency certificate if applicable. Deadlines vary by school, usually in the spring for autumn admission.
Complete Administrative Enrollment: After acceptance, you will need to complete administrative enrollment at the university where the doctoral school is hosted. This involves submitting original documents, proof of funding, and visa-related paperwork. The CNRS International Mobility Office can provide guidance and support for these procedures.

For more information, contact the CNRS International Mobility Office at [email protected] or call +33 1 44 96 40 00. Deadlines for doctoral school applications typically fall between March and May, but vary by school. It is essential to check individual doctoral school websites for exact dates and requirements.

Application Deadlines

CNRS does not have a single application deadline for PhD positions. Instead, deadlines are set by individual doctoral schools and research units. Most doctoral schools open applications in early spring (January-March) for admission in September/October. Some positions may be advertised throughout the year. To find current deadlines, visit the CNRS jobs portal and the websites of relevant doctoral schools. For example, the Doctoral School of Plant Sciences in Paris typically has an application window from March to May. Always confirm with your potential supervisor and the doctoral school.
