My current research project at INRAE focuses on the pea (Pisum sativum) responses to abiotic stresses (mainly water deficit and sulfur deficiency). Using -omics approaches, our goal is to identify genes that may control seed quality and plasticity in response to multi-stress conditions. To this aim, we consider the time of day and gene expression rhythmicity as important factors influencing the observed molecular responses.
Previously, I have been working as a postdoc in the laboratory of Dawn Nagel, where I studied the influence of time of day on the heat stress response of the Arabidopsis circadian transcriptome and translatome. Ahead of that, my PhD project focused on the grain responses to post-anthesis nitrogen and sulfur availabilities, in the diploid wheat species Triticum monococcum.
