Main research interests

My research focuses on the regulation of organelle gene expression during stress responses with a particular emphasis on the role of the members of the pentatricopeptide repeat protein (PPR) family. Through genetics, interactomics and transcriptomics approaches and their integration using bioinformatics and biostatistics, my aim is to infer the plastid and mitochondrial gene networks and to understand how they cope with biotic and abiotic stresses. I’m also interested in how some pathogens can use PPR proteins to manipulate organelle gene expression during infection.
