I have been a CNRS Research Engineer since 2006. At present, I am the technical coordinator of the NIT (Neuroinfomatics and Information Technology) core facility at INT. I’m also a member of two research teams at INT : MECA and BANCO
My activities are anchored in the neuroinformatics field. Mainly, I work on developing new standardization procedures for handling neuroscientific data. I also design innovative machine learning methods for new problems encountered in neuroscience. For this, I collaborate with the Qarma team of the Laboratoire d’Informatique Fondamentale de Marseille. At the moment, my main interest is to understand, model and exploit inter-individual differences measured through multi-modal MRI to better understand brain functions, using a generic framework called inter-subject learning. For all these activities, I am promoting the development of open source code and the sharing of open data.
Some highlights :
