INRAE presentation

The French National Research Institute for Agriculture, Food, and the Environment (INRAE) is a public research establishment under the dual authority of the Ministry of Agriculture and the Ministry of Research.

INRAE is recruiting researchers by open competition and offering permanent position.

It is a major player in research and innovation created on 1st of January 2020. INRAE is a research institute resulting from the merger of INRA and IRSTEA. It is a community of 12,000 people with more than 200 research units and 42 experimental units located throughout France.

The institute is among the world leaders in agricultural and food sciences, in plant and animal sciences, and is 11th in the world in ecology and environment. INRAE’s main goal is to be a key player in the transitions necessary to address major global challenges. In the face of the increase in population, climate change, scarcity of resources and decline in biodiversity, the institute develops solutions for multiperformance agriculture, high quality food and sustainable management of resources and ecosystems.

Work environment, missions and activities

The ECOSYS (functional ecology and ecotoxicology of agroecosystems) Joint Research Unit conducts research on the integrated functioning of agroecosystems and associated ecosystem services.
You will join the Ecotoxicology group and will contribute to two structuring themes of the unit: "Contaminants" and "Biodiversity". The research conducted within the Ecotoxicology group aims to improve understanding of the exposure of organisms to contaminants and the toxic effects on soil organisms at sub-individual, individual or population level in particular. The challenge is to find markers of adaptive processes in the presence of diffuse contamination at sublethal doses to organisms, and to model their impact on ecosystems. To improve the ecotoxicological risk assessment in agroecosystems, your research will be based on an innovative coupling of models of the fate of contaminants in terrestrial systems and "energy distribution" type models, such as extensively used in aquatic ecotoxicology.
Your objective will be to promote a mechanistic and integrated approach in terrestrial ecotoxicology to model the key links between individuals and populations and predict the effects of contaminants on ecosystems through the prediction of the upstream impacts on soil functions. You will make use of the conceptual framework of bioenergetic modelling of the DEB (Dynamic Energy Budget) theory by applying it to target organisms.
You will have the possibility of using data already acquired in the laboratory and thus benefit from the scientific environment of the Ecotoxicology group of the ECOSYS joint research unit on the exposure of soil fauna at individual level and at population or community level.

Training and skills

PhD or equivalent

Candidates must have a PhD or equivalent.
Skills in ecotoxicology and experience in both modelling and experimental approaches are highly recommended. Knowledge on soil would be appreciated. Open-minded and curious, you should be able to work in collaboration with biogeochemists, ecotoxicologists, ecologists, and soil scientists.
Candidates should have a good command of English, and long-term international experience would also be desirable. Successful candidates who have not yet acquired this experience abroad will be required to do so after their probationary period (1st year).

INRAE's life quality

By joining our teams, you benefit from:

- 30 days of annual leave + 15 days "Reduction of Working Time" (for a full time);
- parenting support: CESU childcare, leisure services;
- skills development systems: training, career advise;
- social support: advice and listening, social assistance and loans;
- holiday and leisure services: holiday vouchers, accommodation at preferential rates;
sports and cultural activities;
