During my Ph.D. study (March 2009-December 2013), I have systematically grasped the process of data mining, including data preprocess, supervised and unsupervised learning etc. Currently work at Department of Computer Science and Technology in Xi’an Jiaotong University under the supervision of Prof. Qinbao Song, focusing on feature subset selection for high dimensional data, how to uniformly characterize different data sets, and how should we pick up appropriate data mining algorithm(s) for a given problem. By continuous efforts, I have made a big progress in our research project and a series of interesting results have been published (Such as TKDE, Pattern Recognition, Journal of Artificial Intelligence Research and Intelligent Data Analysis) and will appear in the forthcoming publications. I have been invited as reviewer by international Journal Information Sciences, and international conference on Advanced Data Mining and Applications.
