I am a data visualization scientist at Epsilon Data Management. I recently graduted as a Ph.D in Computer Science from the University of Arizona. My advisor is Dr. Carlos Scheidegger. My current research interests are interactive data visualization, big data analysis and machine learning. I also have research experience in HDFS and data mining during my master’s program.

Before I came to this sunny, lovely Tucson, I received my M.S. in Computer Science from University of Illinois Springfield in Springfield, IL and my B.E. in Computer Science & Engineering from Huazhong University of Science and Technology in Wuhan, China.
