You can find my C.V. here.


Currently, I am final-year Ph.D. student in the department of SEEM in CUHK, under the supervision of Prof. Hong Cheng. Before joining CUHK, I obtained my Bachelor and Master degree both in Computer Science and from Xidian University, in 2011 and 2014 respectively. As a postgraduate student in Xidian University, I was nicely supervised by Prof. Jiangtao Cui and Prof. Hui Li.
