How does the brain integrate information about the subject's environment with internal processes like motivation to produce behavior? What are the neuronal mechanisms and circuits that implement those functions?
To address those questions, I develop models of neuronal networks to study their dynamics and emerging functions, at the microscopic and macroscopic levels. My continuing interest is on distributed representations and computations in neuronal networks. I use network models to interpret neuroimaging and electrophysiological data (spike trains, fMRI, EEG, MEG), in terms of brain communication at the macroscopic level and in terms of neuronal computations at the microscopic level.
The model-based approach is motivated by:
I am involved in CONECT, which aims to bring together neuroscientists around computational methods and questions. It involves seminars and continuous teaching actions, see here for details.
Research is an exciting intellectual adventure, but it is not a "hydroponic" activity, detached from society and the whole Earth environment. There is indeed a growing concern in the scientific community about the implications of research and developed technologies like big data in terms of energetical and social impacts, see for instance the opinion on environmental issues by the of CNRS ethics committee (COMETS). I am thus trying to think how to organize my research in a collaborative manner, while taking into account the foreseen limits. In particular, I am part of Atécopol Marseille that focuses on ecology in academia and around.
