Dr. Gregoire Stik obtained his Ph.D. in Molecular Biology and Life Sciences at the University Rabelais of Tours in 2012. There, he worked with Dr D. Rasschaert studying the transcriptional mechanisms controlling the expression of microRNA during infection by an oncogenic virus. He then moved to the lab of T. Jaffredo (CNRS, UPMC, Paris) in which he focused on the molecular signals controlling the fate of hematopoietic stem cells. Since 2016, he has been part of the Thomas Graf lab (Barcelona, CRG), as a Post Doctoral Fellow.
