About me

I am a third-year Ph.D. student at CUHK Text Mining Group. My advisor is Prof. Lam Wai. Prior to joining in CUHK, I obtained my B.Eng. degree from School of Data and Computer Science, Sun Yat-Sen University in 2016, where I worked closely with Prof. Rao Yanghui and began my research career of natural language processing. I also worked with Dr. Bing Lidong and Dr. Li Piji at Tencent AI Lab on natural language generation (NLG). You can contact me via email.
