Bio (IEEE style)

Edouard Duchesnay received the engineer’s degree in software engineering from École Pour l’Informatique et les Techniques Avancées (France) in 1997, the M.Sc. degree in signal/image processing from Rennes 1 University (France) in 1998 and the Ph.D. degree in signal and image processing Rennes 1 University (France) in 2001.

Since 2008, E. Duchesnay is a research scientist at NeuroSpin/CEA: an MRI neuroimaging center within the CEA. He developed multivariate machine learning algorithms (ML) classification/regression to capture complex relationships to make inferences at an individual level in the perspective of computer-aided diagnosis/prognosis or biomarkers discovery for brain diseases (Duchesnay et al., NeuroImage, 2011).

To investigate genetic influence on the brain, he proposed multivariate latent variable models (Le Floch et al, NeuroImage, 2012) that integrate sparsity and specific feature selection within learning algorithms to alleviate large dimensionality of both imaging and genetic data.

Given the limitations of state-of-the-art sparse algorithms to produce stable and interpretable predictive signatures, he proposed to push forward the regularization approaches extending classical algorithms with structural constraints issued from the known biological structure (spatial structure of the brain and the linkage disequilibrium or pathways of OMICs data) in order to force the solution to adhere to biological priors, producing more plausible interpretable solutions.

The result is a ML library in Python dedicated to high dimensional structured input data (Hadj-Selem et al., arXiv:1605.09658 preprint, 2016, in revision in IEEE-TMI, De Pierrefeu et al., IEEE-TMI, 2017) and ParsimonY that is now used to identify neuroimaging signatures of brain disorders (De Pierrefeu et al., Hum. Brain Mapp., 2018).
