About Me
I am currently a Ph.D. student in the School of Computer Science and Technology at Shandong University, working under the supervision of Prof. Pengfei Hu and Prof. Xiuzhen Cheng. Prior to this, I worked in the Department of Computer Science at City University of Hong Kong under the guidance of Prof. Weitao Xu. I received my B.E. and M.E. degrees from the School of Information Science and Engineering at Shandong Normal University in June 2020 and June 2023, respectively.
My research interests lie in the areas of the Internet of Things (IoT) and mobile computing, with a particular focus on smart sensing, AIoT, and IoT security.
