Research

I am a research scientist hired at INRA in the BIOGER unit in 2006, with a background in plant pathology, molecular biology and functional genomics. My main focus was, and still is, on deciphering fungal-plant interactions. Most of my research experience was devoted to understand fungal pathogenicity and signals produced by the fungus, which induce recognition of “non-self” and disease resistance (avirulence genes or effectors). Since I was hired as a permanent scientist at INRA, I am developing functional genomics approaches on plant-fungi interactions with a particular interest to fungal effectors on the model of interaction Leptosphaeria maculans / Brassica napus. The objective of my research project is to study the possible roles of effectors on pathogenicity towards B. napus (identification, expression, regulation, evolution and functional analysis). To achieve this goal, I develop a pluri-disciplinary project combining bioinformatics, transcriptomics, functional genomics, pathogenicity studies and evolutionary genomics. Recently, I focused part of my researches on the determinism of concerted regulation of effector genes during infection and pointed out on the importance of chromatin status in this regulation. I am co-leading the INRA SPE network REacTION (network on the epigenetic mechanisms that shape plant - Bioaggressors and Symbiotic Organisms interactions)
