Julie PERROY DR2, CNRS

During her PhD in Neurosciences (1998-2001, Montpellier, France) Julie Perroy investigated the function of glutamate receptors in synaptic transmission. It slowly became obvious that one receptor can play multiple functions, each of them being controlled to the interaction with auxiliary scaffolding proteins. Julie thus moved as a post-doctoral fellow in the lab of Michel Bouvier (2002-2004, Montreal, Canada) to be trained in technologies allowing to follow the temporal dynamics of protein-protein interactions in living cells (2002-2004). In 2003, she was appointed to a tenure position at the CNRS, in Montpellier, where she developed a highly sensitive microscopy-based technology to precisely locate, in real time, where interactions occur in neurons. She is now studying glutamate receptosome dynamics in the brain, involved in fine-tuning synaptic transmission and plasticity, which might be crucial for cognitive functions.
