Man's dearest possession is life. It is
given to him but once, and he must live it so as to feel no torturing
regrets for wasted years, never know the burning shame of a mean and
petty past; so live that, dying, he might say: all my life, all my
strength were given to the finest cause in all the world--the work hard
for the Knowledge of Mankind.

I reveived my Ph.D. degree from Emory University and got the Chris Schoettle Graduate Research Award for exceptional graduate research work. I'm currently a joint postdoctoral research fellow at Georgia Institute of Technology and Emory University. I am very fortunate to be hosted by Prof. Jimeng Sun and Prof. Li Xiong.
I am a Ph.D. student in the Department of Math & CS at Emory University. I am so lucky to be supervised by Prof. Li Xiong. I also work closely with Prof. Jian Pei from Simon Fraser University. Before coming to Emory, I got my master's degree from University of Science and Technology of China (USTC) in July, 2012. I am currently working as a research assistant in the AIMS (Assured Information Management and Sharing) group at Emory.
