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

You will join the Animal Genetics and Integrative Biology (GABI) research unit composed of more than 140 permanent staff. It aims at understanding and exploiting the genetic variability of animals to analyze the construction of phenotypes important for animal production and the interactions with microbial ecosystems and the environment, in a broad sense, in a context of agro-ecological transition. You will work in the Genetics and Aquaculture team that focuses on the production of robust and efficient fish in diverse environments. The team analyses the genetic architecture of important traits in aquaculture and the modalities for introducing these traits in genetic improvement programs.

Aquaculture is booming. To reduce the environmental footprint of fish rearing, farmers need robust animals that can produce and reproduce in various, fluctuating environments, by optimizing consumption of food resources and limiting inputs (food, medicine, etc) and waste. Currently, selection targets production traits without taking the trade-off between functions in the allocation of food resources into account.

Your mission will be to understand the functional trade-offs between production traits (growth, quality…) and robustness (survival, stress response, behaviour…) in different rearing systems, conventional or alternative, and to study their genetic determinism. You will pay particular attention to feed efficiency, which is a difficult trait to measure in fish, but a key trait for the joint improvement of economic and environmental performances through an improved valorisation of inputs and waste reduction. You will develop innovative phenotyping methods for this trait and study its genetic architecture. To study the trade-off with other functions, you will develop functional approaches and/or modelling approaches for the allocation of resources and you will be able to rely on a meta-analysis of the data available in the team. With this new knowledge, selection objectives will be revised to foster the agro-ecological transition of aquaculture systems by evaluating not only the economic gains but also the environmental impacts of genetic improvement.

Training and skills

PhD or equivalent

Training in statistical genetics and/or modelling approaches is recommended. Expertise in genomics would be a bonus. Experience or a pronounced affinity for aquaculture would be an additional bonus.

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;
- collective catering.

Registrations have been closed since March 5, 2020. Therefore, you can no longer apply.
