1- Identifying indicators of soil suppressiveness to fungal diseases, in the frame of the European project = Ecofinders (FP7-ENV-2010-264465):  Ecological function and biodiversity indicators in European soils 2011-2015. Objectives : Identification of taxonomic groups associated to soil suppressiveness in a comparative approach using a metabarcoding approach.

2 - Metatranscriptomic approach of the functional diversity of eukaryotic origin in the suppressive soil of Chateaurenard. Funded by AAP-SPE (= dept of Plant Health; INRA) : 30 K€; (Project Coordinator). Objectives : Identification of functional groups involved in Fusarium wilt suppression in a comparative approach using a suppressive and a conducive soil.

3 - Preventive detection risk and biological control of Fusarium wilt of cyclamen Funded by CASDAR-MAAF (Ministry of Agriculture and Forestry) : 45K€; (Co-cordinator of the project). Objectives : identification of a specific molecular marker of the pathogenic form of F. oxysporum toward cyclamen to detect it early and development of a biological strategy to control the pathogenic population.

4 - Characterization of the pathogen inoculum of Rhizoctonia solani, responsible of black scurf of beet (Beta vulgaris) and evaluation of varietal resistance. Funded by CASDAR-MAAF (Ministry of Agriculture and Forestry) 50 K€; (Project Coordinator). Objectives : identification of the pathogenic form of R. solani in production regions in France, Germany, Holland and Belgium to  provide a tool for breeders to select resistance sources in their genotypes.
