Oana Chever is a neurophysiologist, interested in neuronal excitability modulation in physiological and physiopathological states. She started working on cerebral ionic homeostasis during her Ph.D under the supervision of Dr. F. Amzica at Laval University (Québec, Canada), with who she worked on potassium buffering and astrocytes. In 2009, she joined the team headed by N. Rouach (CIRB, Collège de France, Paris) to study the role of astrocytes and astrocytic network on neuronal activities and excitability. From 2014 to 2017, she joined the laboratory of Dr. M. Mantegazza to study the role of interneurons in neuronal network excitability and migraine ethiology. 
Oana Chever has an expertise in electrophysiology and optogenetics, both ex vivo and in vivo. She is currently teaching in Neurosciences and Physiology at the University of Rouen. She’s also working on glioma invasion and neuronal excitability in the team « Astrocytes and Vascular Niche” (DC2N, team leader : Dr Hélène Castel).
