I am a tenure-track assistant professor in the Department of Computer Science at the University of Hong Kong (HKU). My research tackles the core problems in natural language processing (NLP) by designing representation learning algorithms that exploit linguistic structures. My work lies at the intersection of deep learning and structured prediction, with an application focus on syntactic parsing, speech recognition, social media analysis and machine translation. Before joining HKU, I was a senior research scientist at Google DeepMind. I obtained my Ph.D. from Carnegie Mellon University co-advised by Noah Smith and Chris Dyer.
