Short bio

I am a tenured researcher at Inria, where I am part of the Magnet Team (MAchine learninG in information NETworks). I am also affiliated with CRIStAL (UMR CNRS 9189), a research center of the University of Lille.

Prior to joining Inria, I was a postdoctoral researcher at the University of Southern California (working with Fei Sha) and then at Télécom ParisTech (working with Stéphan Clémençon). I obtained my Ph.D. from the University of Saint-Etienne in 2012 under the supervision of Marc Sebban and Amaury Habrard.

You can find more information in my CV or on my LinkedIn profile.

Research interests

My main line of research is in statistical machine learning. I am particularly interested in designing large-scale learning algorithms which allow a good trade-off between computational complexity (or other "resources", such as privacy or communication) and statistical performance.

My current research focus includes:

  • distributed / federated / decentralized learning algorithms
  • privacy-preserving machine learning
  • graph-based methods
  • optimization for machine learning
  • similarity and distance metric learning
  • statistical learning theory
  • applications to NLP and speech recognition
