Resume

From 2011 to the end of 2012, I was a post-doctoral Associate at Duke university working with Rebecca Willett in the Network and Imaging Science Laboratory (NISLab). In 2010, I finished my PHD in Statistics under the supervision of Dominique Picard and Erwan Le Pennec at the Laboratoire de Probabilités et de Modélisation Aléatoire (LPMA ) in Université Paris Diderot.
My thesis was about the denoising of digital images combining patch-based method and statistical aggregation. The full manuscript can be found in the section papers. I am especially interested in topics such as: high dimensional regression, aggregation of estimators, patch based denoising methods and non-parametric regression.

Research

You can find my papers and my talks slides. I also collect here software and other numerical elements for reproducing the experimental results presented in my papers.
