I am a PhD student of Computer Science department at The University of North Carolina at Chapel Hill under the supervision of Prof. Alex Berg . I received my B.S. at Nanjing University at China in Jul. of 2009. Then, from Aug. 2009 to Jul. 2011, I worked as a research assistant at Carnegie Mellon University for two years with Prof. Fernando De la Torr and Prof. Alex Hauptmann . From Sep. 2011 to May 2012, I did one year PhD study at Computer Science department at UNC Chapel Hill under the supervision of Prof. Svetlana Lazebnik . From May 2012 to Aug. 2012, I was a research intern at the Core Location team under iOS Department at Apple , and I presented my project to SVP Scott Forstall . From Sep. 2012 to Aug. 2013, I did one year PhD study at Computer Science department at Stony Brook University under the supervision of Prof. Alex Berg , then I moved with him back to UNC Chapel Hill in Aug. 2013. I did a great internship at Google Mountain View in 2014 summer. Our team GoogLeNet won the classification and detection challenge in ILSVRC2014 . My research speciality is computer vision. The main focus of my current research include:
Abrige the semantic gap of image understanding
Recognize and detect object from large scale image/video dataset
