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:
- 2021: With Julia Sprenger, we have drafted a BIDS Extension Proposal for animal electrophysiology and we are seeking feedback! Go here!
- 2021: Virginia Aglieri’s paper on speaker identification studied with fMRI and machine learning decoding techniques has been published!
- 2020: another journal paper by Qi Wang: Inter-subject pattern analysis for multivariate group analysis of functional neuroimaging. A unifying formalization, which is available here!
- 2020: I have initiated the creation of a new INCF Working Group aimed at standardizing the organization of neuroscientific data obtained with animal models.
- 2020: Akrem Sellami’s paper on deep learning fusion of multi-modal MRI data to improve predictive models of individual differences has been accepted to IJCNN!! Find the paper here

- 2019: I co-organized (and hosted at INT) the INCF-sponsored GEANT workshop, dedicated to data management practices in neuroscience
- 2018: our multi-modal MRI data set InterTVA is online on the OpenNeuro portal; it is aimed at studying inter-individual differences in voice perception and benchmarking multi-view machine learning algorithms

- Two papers that include new applications of inter-subject learning: the first one (2017) to quantify the power of EEG features in newborns to predict language acquisition (Enhanced Neonatal Brain Responses To Sung Streams Predict Vocabulary Outcomes By Age 18 Months) and the second one (2018) to demonstrate structure-function relationships (Anatomo-functional correspondence in the superior temporal sulcus)
- 2017: yet another demonstration of the usefuleness of our graph-kernel approach to design predictive models, this time for diffusion-MRI: Learning from Diffusion-Weighted Magnetic Resonance Images using graph kernels
- 2016: a new paper using our graph kernel has been accepted to Medical Image Analysis: Structural graph-based morphometry: A multiscale searchlight framework based on sulcal pits
- 2015: I have, finally, defended my PhD thesis in machine learning applied to neuroimaging: A multi-source perspective on inter-subject learning. Contributions to neuroimaging.
- 2015: our ANR project LIVES (Learning with Interacting ViEwS) has been funded; I am the coordinator of the INT team and we will design and apply multi-modal machine learning methods on MRI data (anatomical, structural, resting-state, task-functional)
- 2014: our graph kernel paper has been accepted in Plos ONE: Graph-based inter-subject pattern analysis of fMRI data; the source code and dataset are available here
- 2013: release of Vobi One, the first open source software suite dedicated to the processing of functional optical imaging; the paper is available here
- 2013: co-PI of the PEPS BMI CAMPA (CAractérisation Multimodale des déficits sensori-moteurs Post-AVC) project;
- 2011: organizer and chair of the MLNI workshop, which gathered leading researchers in machine learning and neuroimaging;
- 2010-2012: PI of the Neuro-IC GRABBR (GRAph-Based Brain Reading) project;
- 2009: publication of our PNAS paper on ICA and fMRI, which includes some the work I did during my six years at Princeton University.
