Qing Da (Q. Da)                    / linkedin

I received my B.Sc. degree and M.Sc. degree from Nanjing University, China in 2010 and 2013 respectively. Since Sep. 2013, I become a Ph.D. student in the LAMDA Group, Nanjing University, under the supervision of Prof. Zhi-Hua Zhou.

In Jan. 2015, I aborted the Ph.D. procedure and joined the search algorithm team at Alibaba. Now I am a senior algorithm expert of the AI team within the search department of Alibaba.

Research Interests

My research interests include machine learning, data mining.
