About Me
I am an Associate Professor at the School of Computer Science, China University of Geosciences, Wuhan, China. I received my Ph.D. in Computer Application Technology from Wuhan University in 2015 and was a visiting scholar at the Singapore University of Technology and Design (SUTD).
My research explores machine vision, image processing, and artificial intelligence, with particular interests in visual localization, 3D vision, and multimodal perception. I have led more than ten research projects, published 40+ SCI-indexed papers as first or corresponding author, obtained 10+ authorized invention patents, and authored two academic monographs.
