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 Ecophysiology and Functional Genomics of grapevines (EGFV) joint research unit conducts research on vine ecophysiology, biochemistry, physiology, molecular biology, and (epi)genetics.
You will be part of the integrative biology group working on the functioning of grafted vines and the determinants of the quality of the grape berry in relation to environmental constraints and genetic diversity. The vine is a grafted plant and its functioning thus depends on numerous interactions between the genotype of the scion and that of the rootstock.
You will develop models describing the morphological and functional responses of the root system to soil water and nitrogen availability, but also according to the internal trophic status of the scion in order to characterize or design new rootstocks to meet the current challenges in viticulture (low inputs, climate change). The ecophysiological models developed will also allow virtual phenotyping to be performed on a range of contrasting environments and new ideotypes to be designed and evaluated in silico.
You will benefit from local modelling expertise, innovative phenotyping instruments under controlled conditions or in the field located nearby, and recent datasets on the characterization of the response of rootstocks to the availability of water, nitrogen or phosphorus.
You will interact with the networks and modelling platforms of the AgroEcoSystem division and draw on collaborations with other laboratories locally, nationally and internationally.

Training and skills

PhD or equivalent

Candidates must have a PhD or equivalent.
Experience in dynamic modelling of complex biological systems and knowledge in plant ecophysiology are highly recommended. Good command of object programming languages would be highly desirable, as well as knowledge of modelling platforms (GroIMP, OpenAlea).
You should be able to interact with your fellow biologists.
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;
