Cécile Charrier

Charrier has said that she knew from high school that she wanted to become a neurobiologist.[2] She earned her master's degree in neuroscience and defended her doctoral thesis in neuroscience, supervised by Antoine Triller, in 2009 at the Pierre and Marie Curie University, which became part of Sorbonne University in 2018.[1] She went on to do three post-docs, one at Inserm, then at University of North Carolina and finally at Scripps Research Institute in La Jolla, California. There she studied the SRGAP2C gene that appeared at the time when Australopithecus and Homo separated, around 2.4 million years ago. Charrier's research demonstrated the crucial role that this gene played on the "development of characteristics specific to human synapses, a discovery that determined her subsequent career."[2]

She returned to Inserm in 2013 as a tenured researcher[3] and since 2014 she has worked with a research group at the Biology Institute of the Ecole Normale Supérieure (IBENS) where she leads own team of researchers.[2][3]

In 2021, the French Academy of Sciences gave her its Irène Joliot-Curie Young Female Scientist of the Year award for her work, citing:[2][4]

"The overall theme of Charrier's research is to understand the fundamental mechanisms of synapse development and plasticity and to identify regulations that only exist in humans. In parallel, her work has also focused on technological developments such as the development of a three-dimensional optical and electronic microscopy technique that allows the ultrastructural and quantitative characterization of synapse subtypes.[4]

Charrier actively encourages the employment of more women in biology and research.[2][4]
