I am a research scientist at Facebook Conversational AI. My current research topics are NLP, dialog and multi-modal learning. I am also interested in general machine (deep) learning, non-convex optimization and their applications in NLP and CV.

Before joining Facebook, I worked as a researcher/scientist at GE global Research and Microsoft AI and Research on digital signal modeling (time series, acoustics), NLP, CV, reinforcement learning, personalization and Ads. I got computer science PhD from University of Maryland Baltimore County and bachelor’s degree in Math from Fudan University.
