Arijit Ghosh

I am a (happy) 2nd year Ph.D. student in Computer Vision at École Nationale des Ponts et Chaussées (IMAGINE Lab) and École Polytechnique (VISTA Lab) under the supervision of David Picard and Vicky Kalogeiton. My main research interest lies in multi-modal generative models and the generalization of such multimodal models. Prior to my Ph.D. I completed my M.Sc. in Artificial Intelligence from University Erlangen-Nürnberg, Germany.
