I am the Deputy Manager of the Data Analytics Lab at Xerox Research in Grenoble, France. My role involves the scientific coordination of our research activities around analytics including machine learning, computer vision and language technologies.

I received my Engineering degree from Telecom ParisTech in 2000 and my PhD in Computer Science from EPFL in 2004. In 2000-2001, I was a Research Engineer with Panasonic in Santa Barbara, CA, working on speech and speaker recognition. From 2005 to 2015, I was with the computer vision group of Xerox Research in Grenoble, France, first as a Research Scientist then as Principal Scientist and Manager. From May 2015 to June 2016, I was the Director of the Facebook AI Research (FAIR) Lab in Paris.

My research has found applications in several business verticals including Business Process Outsourcing (BPO), Transportation, Retail or Communication and Marketing. It also won several awards in public competitions such as PASCAL VOC, ImageNet and ImageCLef.
