Research statement: I use tools from statistical physics and machine learning to understand how computing abilities emerge from the interactions of recurrently connected networks of neurons. This understanding leads to the production of mathematical models that allow, in collaboration with experimental neuroscientists to study the functioning of biological neural networks.

Short-bio: In 2011 I have received the master « theoretical physics of complex systems » from ENS Cachan. I then worked between Paris (Neurophysics lab) and Chicago (Neurobiology department) as a neuroscience PhD student. From 2014 to 2017 I worked as a post-doctoral fellow in the Laboratory of Theoretical Physics of ENS, and from 2018 to 2020 in the cognitive science department of ENS.

Keywords: theoretical neuroscience – machine learning – recurrent neural networks – cortical processing.
