I am currently an Associate Research Professor in the School of Navigation at Wuhan University of Technology (WUT). I recieved my Ph.D. in Traffic Information Engineering & Control from WUT in 2020, where I am advised by Prof. Kezhong Liu in the Martime Intelligent Transportation System Group. I was a Research Scholar in the Dept. of Computer Science, The University of Texas at Dallas, under Advisor Prof. Cong Liu during November 2017 to December 2018. From July 2023 to July 2024, I am honored to be a visiting scholar at the School of Computer Science and Engineering, Nanyang Technological University, under the guidance of Prof. Jun Luo. My research work has been focusing on intelligent sensing techniques and deep learning algorithms for indoor localization, human navigation and activity recognition in mobile environment, i.e., cruise ships. My current areas of interest include wireless networks, mobile computing, machine learning and computer vision.
