Controllable information extraction, Controllable text generation, Natural language understanding
I am a Postdoctoral researcher advised by Prof. Thomas Lukasiewicz in the Intelligent System Lab, University of Oxford. Previously, I was an NLP research scientist in Apple. While at Apple, I am responsible for Siri’s module, such as domain classification and chit-chat dialogue. Before that, in 2018, I obtained my PhD degree and graduated from Peking University, China, where I worked with Prof. Zhifang Sui, Prof. Baobao Chang, and Prof. Sujian Li. I also served as a research assistant in Microsoft Research Asia, working with Chin-yew Lin, Lintao Zhang, and Qi Chen. During my PhD period, I majored in information extraction and text generation. I have published many first-author papers in top conferences of NLP, such as ACL, EMNLP, NAACL, AAAI, etc. My research interest focus on natural language understanding and controllable text generation.
