Research interests

I place at the heart of my research the restoration of the quality of agricultural soils and water through virtuous treatments and recycling practices.
I study microbiomes at the water/soil interface during irrigation with treated wastewater from wastewater treatment plants (reuse) and during the spread of composts and methanization digestates.
My research questions focus on the inactivation of pathogenic species by the biotic pressure of microbial community, and on the coalescence of communities allowing the installation of new microbial species and functions.

• Coalescence of bacterial communities when digestates and composts are spread on soil
• Impact of treated wastewater irrigation (reuse) on the soil microbiome
• Survival of pathogenic bacteria during biological treatment of organic residues and effluents - biotic and abiotic factors
• Study of biofilms and pathogenic species in irrigation systems fed by treated wastewater
• Viable but non-cultivable state of pathogenic species
• Impact of electromagnetic treatment of water on microbial diversity
• Use of molecular tools for environmental monitoring of pathogens
• Bioaerosols
