陈桐飞

I am a Senior Researcher at Microsoft Semantic Machines, working on building next-generation conversational AI systems.

I obtained my Ph.D. in Computer Science at Center for Language and Speech Processing at Johns Hopkins University under advisor Prof. Benjamin Van Durme. Prior to Hopkins, I obtained my B.Sc. in Computer Science from Peking University.

In addition to natural languages, I'm also interested in programming languages: I design expressive, typesafe DSLs for various domain applications (e.g. deep learning).

My full CV can be found here.
