Thierry Galli is a neuroscientist, Inserm research director, and Director of the Institut de Psychiatrie et Neurosciences de Paris (IPNP), France. His research focuses on how brain cells communicate, particularly through mechanisms of secretion and intracellular trafficking. He investigates how these processes are altered in neurodegenerative diseases such as Parkinson’s disease, as well as in glioblastoma, an aggressive brain tumor. His work aims to understand the earliest cellular changes that occur before symptoms appear. By identifying molecules released by cells at these early stages, he seeks to discover new biomarkers and therapeutic targets.
