BIOlogie et GEstion des Risques en agriculture - Champignons Pathogènes des Plantes


Welcome to Sabine, Carolina and Camilla!

5th March 2018


Sabine Cadoux joins us as engineer for a one-year period. She will work for the FSOV project MABRUNE on the fine mapping of QTLs resistance to wheat rust, Puccinia triticina. She will develop recombinant populations for several QTLs and select recombinant plants using molecular markers, under the supervision of Henriette Goyeau and Thierry Marcel.

Carolina Orellana-Torrejon joins us for a MSc 6-month project. She will work on the impact of cultivar mixture on the dynamic of a varietal resistance breakdown and the transmission of a virulence in Zymoseptoria tritici local population, under the supervision of Frédéric Suffert and Sandrine Gélisse.

Camilla Langlands joins us also for a MSc 6-month project. She will work on the genetic determinism of the pathogenicity of Zymoseptoria tritici against a resistant wheat cultivar and the mapping of QTLs of pathogenicity in a recombinant pathogen population, under the supervision of Thierry Marcel and Nicolas Lapalu.

A permanent research position CR2 (junior researcher) is open in our group 

29th January 2018

post CR2

Permanent research position CR2 in plant disease epidemiology on "Epidemic recurrence and management of varietal resistance"

Key activities and required skills - The goal of the host research team is to improve the efficacy and durability of varietal resistance against fungal diseases of wheat. The successful candidate will lead projects aiming to characterize the epidemiological processes involved in the multi-annual recurrence of epidemics and pathogen population dynamics. He/she will integrate these processes and their influencing factors to design and evaluate varietal resistance management strategies. He/she will base his/her research on multi-scale experimental strategies (plant, field, landscape) in close collaboration with other team members working on host-pathogen interactions, evolution of pathogen populations and processes involved in the inter-annual transmission of virulence, and will collaborate with modellers. Skills in phytopathology and epidemiology, ecology or dynamics of microbial populations in an agronomical context are highly recommended.

Training required - PhD or equivalent, preferably in plant epidemiology, phytopathology, biology of fungal populations. Skills in demogenetics, evolution/ecology of microbial populations, and agroecology would be a 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).

Deadline for submitting applications:
- 5th March 2018, at 5pm (Paris time), for online applications

Location: INRA Jouy-en-Josas (MaIAGE) or INRA Grignon (BIOGER) or INRA Sophia Antipolis (Institut Sophia AgroBioTech). More details are available here.

Candidates must have a strong interest in plant disease epidemiology, modelling programming and/or statistical analyses. The 6-month positions are available from February/March 2018 to August/September 2018 (dates are more or less flexible). Applicants should contact suzanne.touzeau@inra.fr and florence.carpentier@agroparistech.fr.


Engineer position (12 months) - "Assessment of the effect of crop diseases and pests on yields in France" / CDD IE (12 mois) - "Evaluation de l’effet des maladies et ravageurs des grandes cultures sur les rendements en France"

2nd October 2017  [the position is closed]


We are searching an engineer to work during one year on the assessment of the effect of crop diseases and pests on yields in France. Candidates must have competence in modelling, programming and statistical analyses, with a strong interest in agronomy or plant protection. The position can be filled as soon as possible. More details are available here. Applicants should contact corentin.barbu@inra.fr and florence.carpentier@agroparistech.fr.
