Hi! I am Jiazhan (Jamie) Feng, a Ph.D. student at the School of Intelligence Science and Technology, Peking University, advised by Prof. Dongyan Zhao and Prof. Rui Yan. I am also a Visiting (Recognised) Student at the University of Oxford, advised by Prof. Yee Whye Teh.  Before that, I was a research intern at Microsoft Research Asia (MSRA), and a research intern at Microsoft Azure AI, Redmond, advised by Dr. Ruochen Xu, Dr. Yelong Shen and Dr. Weizhu Chen.

Feel free to email me for any form of academic cooperation. Cheers! ^_^

Research Interest

I am fascinated by real-world problems related to natural language processing, especially how to usher conversational AI models into the world of human knowledge. Now I am conducting research on the following problems:
