I joined Facebook in September 2014, as a Research Scientist in the AI Research Group. In the previous past four years I was a researcher at the Idiap Research Institute in Switzerland, leading the Applied Machine Learning group. Previously, I have spent six years at NEC Labs in Princeton, NJ. My current interests are around deep learning in general, with applications in natural language, image and speech processing. I also hack Torch (a machine learning library) on my free time. I received my PhD from University of Pierre & Marie Curie in Paris, while achieving it under the supervision of the Bengio brothers (Idiap in Swizterland, and University of Montreal).
