Background: I did my PhD thesis in Dr C. Dargemont’s lab under her guidance at Institut Curie and Institut Jacques Monod. My thesis focused on the molecular mechanisms of the nuclear export of proteins and RNAs. I then focused on the role of ubiquitine proteasome system in the regulation of the nuclear export of mRNAs and in the autophagy, using Saccharomyces cerevisiae as model organism.
My current work: I joined Dr. L. Pintard’s lab in February 2014. The general goal of my research concerns the role of the ubiquitin proteasome system in the regulation of cell cycle during early development using C.elegans as model organism.
