Short bio:

In 2011, I finished my Ph.D which I conducted within the Sierra Team of the Département d'Informatique of École Normale Supérieure. I had the chance to be co-supervised by Francis Bach and Jean-Yves Audibert. I then spent a great year as a postdoctoral researcher with Alexandre d'Aspremont at Ecole Polytechnique. From January 2013 until May 2014, I worked for Criteo where I was in charge of improving the statistical and optimization aspects of the ad prediction engine. Until April 2019, I worked as a senior machine learning scientist at Amazon, Berlin, focusing on online learning, Bayesian optimization and auto ML. I am now a senior research scientist in the Berlin Google Brain team.

Research interests:

My research interests revolve around machine learning, statistics, (convex and Bayesian) optimization, (structured) sparsity, auto-ML and the uncertainty modelling in neural networks.
