Présentation

My research projects cover fundamental questions about disease epidemics all while being rooted in concerns with direct importance for production in the field. I collaborate with horticultural sectors that encounter fungal diseases. With the overall objective of optimizing the reasoned protection of crops, my work aims to 1) -identify and characterize pathogens, 2) - identify reservoirs of inoculum and 3) - evaluate the aerial dissemination at local to global scales. To accomplish this, I design experimental set-ups and develop sampling strategies and methodologies for the quantification of airborne inoculum and its phenotypic and genetic characterization. I work mostly on diseases caused by fungi with broad host ranges including *Botrytis cinerea* (grey mold), *Sclerotinia sclerotiorum* (white mold), and *Fusarium proliferatum*. Whereas *B. cinerea* and *S. sclerotiorum* have caused recurrent epidemics for decades on various horticultural crops in France – importantly on tomato and lettuce, respectively – *F. proliferatum* has only recently emerged as a pathogen on garlic.
