My research focuses on multimedia analysis, computer vision and machine learning. I was awarded as the Peiyang Elite Scholar. Till now, I have published 80+ papers in the field of multimedia analysis and understanding, including several regular papers in IEEE Transactions (e.g. T-PAMI, T-IP, T-MI, T-C), CCF-A conferences (e.g. CVPR, ACM MM), ESI (3%) high citation papers. I was awarded with Student Participant Grant by ACM Multimedia Conference. I have applied 30 patents, 17 of which were approved and 1 of which underwent technology transfer. I serve as the guest editor of TBD, PR, JVCI, and so on. I serve as the co-chair of 2016 & 2017 CVPR Workshop. I was the co-organizer of 3D model retrieval evaluation in SHREC 2015&2016. I also serve as the TPC of many international conferences, the reviewer of several SCI journals.
