I am a research scientist in Facebook working on conversational AI. My research interests focus on machine learning for natural language understanding and spoken dialog system. I received my PhD from Carnegie Mellon University in 2018 where I worked with professor Ian Lane on deep learning and reinforcement learning for task-oriented dialog systems. Before joining Facebook, I interned at Google Research working on end-to-end dialog learning. Prior to that, I received my bachelor’s degree in electrical engineering from Nanyang Technological University, Singapore.
