I am a researcher at CNRS, working in the Sierra Team, which belongs to the DI/ENS (Computer Science Department of École Normale Supérieure). I am also member of the European network PASCAL.
I am member of the ANR Project Calibration. Until August 2012, I was leader of the ANR Project DETECT, which belongs to the 'Young researchers' program.

Main research interests:

Statistical learning, non-parametric statistics
Resampling, V-fold cross-validation, bootstrap
Data-driven calibration of learning algorithms, model selection
Confidence regions and multiple testing in high dimension
Interaction of the above with Computer Vision

CV short/long - My Ph.D. - Talks (with some slides and videos) - Teaching and popularization - Miscellaneous

Teaching

Spring 2013: Statistical learning (with F. Bach) - Master 2 Probability and Statistics - University Paris-Sud (Orsay)
