Minibio
I am a control and electronics engineer by training. During my PhD in applied mathematics, I dived into dynamical systems and neuroscience. After two postdocs on computational and clinical neuroscience, I joined to the Cophy Team as an Inria researcher. My research activities aim at deciphering the computational underpinnings of physiological, pathophysiological, and psychological processes, and improving the care of patients with neurological disorders.

Outside of the lab...
you can see me cycling around or painting somewhere in the city. I love trying new cocktails but my favorite remains Negroni.
