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 coordinator of the ICM Center of Neuroinformatics, and scientific director of the ICM platform of biostatistics and bioinformatics.

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

Softwares

Deformetrica

Deformetrica is a collaborative project which provides cutting-edge statistical tools to analyze image and image-derived data with deformations. Input data may be images, curve- or surface- meshes in 2D or 3D. It can be used for:

  • Registration, namely the superimposition of images or geometric primitives by the computation of an optimal deformation
  • Atlas Construction, namely the estimation of an geometrical model from a series of example data, and summary of the variability in shape of this model across the samples
  • Regression, namely the construction of a dynamic model from a series of data indexed by time (or other co-factors)
  • Dynamic atlas construction, namely the construction of a dynamic model from longitudinal data, i.e. a set of subjects or objects observed at multiple time-points.

For more details, visit www.deformetrica.org


Exoshape

Developed within the European project Health-e-Child, the software ExoShape is a set of Matlab functions and Mex-files to perform statistical analysis of sets of curve and surface meshes. Its development was stopped in 2010, as the more ambitious Deformetrica project took over.
