From the beginning of my career, I have been interested in better understanding the diseases at the molecular level. I received my PhD in cancer biology from the Toulouse University in 2011. My dissertation work in the lab of Bernard Payrastre at the Center for Physiopathology of Toulouse Purpan dealt with the cellular function of the lipid second messenger phosphoinositides in the context of Shigella flexneri infection, which is responsible for the dysentery in humans, and invasion of anaplastic large cell lymphomas. I then joined the lab of Mark Ginsberg at the University of California San Diego, where I conducted work on signaling events that control the affinity of the integrin adhesion receptors for their cognate ligands, an event central to their function in blood cells. This postdoctoral stage (2012-2018) was sponsored in part by a Postdoctoral fellowship and a Career Development award from the American Heart Association. My work led to establish the emerging paradigm that signaling events in leukocytes operate in both a cell-type and integrin-specific manner, thereby providing unique avenues to manipulate recruitment of particular leukocytes into specific tissues. In 2019, I was recruited to CNRS as a permanent researcher to work on integrin-mediated adhesion in immune cells in the lab of Isabelle Maridonneau-Parini at IPBS. My research program received financial supports from the Fondation de France, Fondation Toulouse Cancer Santé and a Marie Sklodowska-Curie Individual Fellowship – Reintegration panel. In 2021, I was awarded the ATIP-Avenir funding program in partnership with the Fondation ARC to launch my own research team on the dynamic regulation of immune cell integrins and the interplay with cancer pathogenesis and chronic inflammatory diseases at IPBS.
