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 CRCN will be assigned to UMR-SayFood. He will work in Thiverval-Grignon (78850), then Palaiseau (91120) from September 2022. SayFood (Paris-Saclay Food and Bioproduct Engineering Research Unit) is a Joint Research Unit newly created by INRAE and AgroParisTech, by the merger of UMR GMPA (Food Process Engineering and Microbiology) located in Grignon and GENIAL (Food Process Engineering) located in Massy and Paris. This unit hosts 127 employees (permanent staff) and will be located in 2022 in the Paris-Saclay research and innovation ecosystem, unique in Europe, located in Palaiseau (Ile de France).
The mission of UMR Sayfood is to acquire new scientific knowledge and to propose new approaches in product and process engineering. Its ambition is to contribute to the development of new healthy and sustainable food systems by working in interdisciplinarity on the "design-consumption" continuum. To conduct its research, Sayfood draws on a unique set of skills spanning food science, microbiology, process engineering and consumer science. His work has applications in the food industry, agro-industries and biotechnology.
The objective of the Food Microbial Communities (CoMiAl) team, in which CRCN will work, is to better understand the structure and functionalities of the microbial communities in fermented foods. To do this, it uses skills in the fields of genomic analyzes (bacteria and yeasts), microbial ecology and physiology, and the characterization of microorganisms / surface and microorganisms / microorganisms interactions. Metadata integration allows to get an integrated view of the functioning of these microbial communities in the food matrix.
One of the major challenges for the team is to design efficient microbial communities, developing functions of interest, in fermented foods.
Your approach should propose , through the understanding of key ecological phenomena and expert knowledge, microbial assemblages (synthetic ecology) expressing the desired functions, in particular in new food matrices (eg: integration of new protein sources).
You will described microbial communities functioning through heterogenous data integration including (meta) -omics applicable to food matrices (integrative bioinformatics).
To explore the structuring and functioning mechanisms of microbial communities, you will rely on the study of reduced microbial communities models made up of less than ten species (eukaryotes and prokaryotes), developed in the team, and representative of real products with higher biodiversity.

The CRCN will be recruited at the UMR SayFood. He (she) will initially be assigned to the AgroParisTech site of UMR SayFood in Thiverval-Grignon (78850),then Palaiseau (91120) in september 2022 where UMR-SayFood will be relocated on the new AgroParisTech-INRAE ??Campus.
