I am currently an Assistant Professor in the Department of Computing at The Hong Kong Polytechnic University (PolyU). I received my Ph.D. degree in Computer Engineering from Stony Brook University, where I had the privilege of working with Prof. Yuanyuan Yang. Prior to that, I earned a Bachelor's degree in Telecommunications Engineering from Xidian University.
