My research focuses on computer vision and machine learning, especially learning based hashing algorithms and their applications in visual retrieval and recognition problems. I have published 100+ papers in CVPR, ICCV, MM, SIGIR, TPAMI, TIP, TMM, TCSVT, etc. I have served as a regular PC member for ICCV, ACM MM, AAAI, ICMR, ICPR, MMM, journal reviewer for IEEE TIP, TNNLS, TKDE, TMM, TCYB, TCSVT, guest editor for Neurocomputing, PRL, NPL, special issue chair for ACPR'17 and special session organizer for MMM'16, ICMICS'16. I am the recipient of the Best Paper Award Honorable Mention at ACM SIGIR 2016 & ACM SIGIR 2017 and the World's FIRST 10K Best Paper Award - Platinum Award at IEEE ICME 2017.
