I am a senior researcher (roughly equivalent to associate professor with tenure) at INRIA working in the Willow project at the Department of Computer Science of the Ecole Normale Supérieure .My thesis dealing with efficient visual search of images and videos was awarded the Sullivan Thesis Prize and was short-listed for the BCS Distinguished Dissertation award - the prize for the best Computer Science thesis in the UK. Before coming to France I spent six months as a post-doc in the Computer Science and Artificial Intelligence Lab (CSAIL) at MIT, working with Prof. William Freeman. My research is in com puter vision - a branch of computer science and engineering that aims at extracting information from images. I am particularly interested in visual search and recognition applied to large image and video collections.
