Postdoctoral Researcher (October 2015 -- Now)


Profile 
I received B.S. and M.S. degrees from Department of Computer Science, Nankai University, China, in July 2005 and July 2008. I received Ph.D. degree from Graduate School of Informatics, Kyoto University, Japan, in September 2013.

On one hand, my current research topic is related to quality control in crowdsourcing and crowdsourcing in data engineering. On the other hand, in the project of university of big data, which is a platform for data analysis competition, I take responsibility of data preparation of competitions and will take part in the development of this platform.
