I am a second-year PhD candidate in the Faculty of Electronic Information And Electrical Engineering at Dalian University of Technology, supervised by Professor Hongyu Wang. I am currently working with Professor Ming-Hsuan Yang as a visiting student (09/2013-03/2015) in University of California, Merced. I received my B.E. from Dalian Maritime University in 2010.
