Bio

I am a fourth year Ph.D. student at Sierra and Willow. I am supervised by Simon Lacoste-Julien, Ivan Laptev and Josef Sivic. I graduated from Ecole polytechnique and Telecom ParisTech in 2015 and got a Masters Degree in Mathematics, Machine Learning and Computer Vision (MVA). My work focuses on structured learning from video and natural language. More details can be found in my resume.
