Short Bio

I am currently a Ph.D. student with the joint training program leading to dual Ph.D. degrees, affiliated with the Department of Electrical and Electronic Engineering, The Hong Kong Polytechnic University, Hong Kong SAR, and the School of Electronics and Information, Northwestern Polytechnical University, Xi'an, China. I received my M.Eng. degree from the School of Marine Science and Technology, Northwestern Polytechnical University, Xi'an, China, in 2022, and my B.Eng. degree from the School of Electrical Engineering and Automation, Jiangxi University of Science and Technology, Ganzhou, China, in 2019.
My research interests encompass AI Safety and Trustworthy AI, with a particular focus on their applications in Large Language Models, Computer Vision, and Remote Sensing. I am dedicated to advancing these domains by ensuring that AI systems are not only effective but also safe, reliable, and trustworthy.
