Welcome!

I am heading the joint Inria/ICM Aramis Lab with O. Colliot at the Brain and Spine Institute (ICM) located within the Pitié-Salpêtrière hospital in Paris. I am also the founding director of the ICM Centre for Neuroinformatics , and scientific director of the ICM platform for data management and analytics.

My team focuses on the development of new statistical and computational approaches for the analysis of image data and image-derived geometric data such a surface meshes. We have contributed to the definition of statistical analysis methods for spatiotemporal measurements in longitudinal studies, where sets of geometric objects (or structured data) are observed at multiple points in time.

Our research is essentially motivated by, and applied to the study of the structure and function of the human brain. It makes accessible the wealth and complexity of information contained in multiple modalities of medical images via virtual representations of the brain, and allows the tracking of these representations during ageing or disease progression.

I received the Young Investigator Award from the conference MICCAI in 2008 and the second Gilles Kahn Award for best dissertation in computer science in 2010. In 2015, I was awarded an ERC Starting Grant from the European Research Council. I have been fellow of the Paris AI Research Institute (PRAIRIE) since 2019.

I am associate editor of IEEE Transactions on Medical Imaging (IF 6.1), and Neurons, Behavior, Data Analysis and Theory (NBDT).

Software

Deformetrica

Deformetrica: learn from shapes is a software project which provides statistical tools to analyze shape data using space deformations. Input data may be images, curve- or surface- meshes in 2D or 3D without the need for point correspondence. It can be used to build dynamical model of shape changes from longitudinal shape data sets. Brief introduction in this Medium post.

Leaspy

Leaspy: learn spatiotemporal patterns in python is a software project which allows the construction of personalized models of progression from longitudinal data sets, e.g. multiple subjects observed at multiple non-corresponding time-points. Data may be sets of biomarkers, or data distributed at the nodes of a fixed mesh. Brief introduction in this Medium post.
