I am part of the Language Translation and Technology (LATTE) team of Facebook AI. I lead our Natural Language Understanding efforts. My team's ambition is to build General NLP tools that can learn to perform new tasks with little or no supervision. We are also building tools for Cross-Lingual Understanding that make it possible to learn to perform a task (such as classification) on one language and apply it on other languages without any additional training data.
I previously worked on Machine Translation also as part of LATTE. Before that I spent 3 years working on Search-related NLP problems at Facebook. I helped ship several improvements to Search including fuzzy name matching, keyword search and trending topics.
