My research activity is focused on metabolomics applied to the study of grapevine trunk diseases, a major challenge for the sustainability of the viticulture sector. As a specialist in both untargeted and targeted metabolomic approaches, I develop and apply state-of-the-art analytical tools to decipher the complex interactions between grapevine and the fungal pathogens responsible for these diseases.

 My work aims to elucidate fungal infection mechanisms at the metabolic level by identifying pathogen-induced perturbations of grapevine metabolic networks, as well as metabolic signatures associated with fungal virulence strategies. In parallel, I investigate grapevine resistance and tolerance mechanisms, whether constitutive or induced, in order to identify key metabolites and metabolic pathways involved in plant defense responses.

 A major research axis also concerns the evaluation of innovative biological solutions, particularly mycorrhization, and their effects on grapevine physiology and metabolism. The objective is to understand how these symbiotic interactions modulate plant metabolic responses, enhance resilience to trunk pathogens, and contribute to the development of more sustainable disease management strategies.
