About Me

I am a PhD student with the Department of Electrical and Electronic Engineering (EEE), The Hong Kong Polytechnic University, under the supervision of Prof. Haibo Hu (ASTAPLE). I received the Master’s degree in computer technology with the School of Cyber Science and Engineering, Southeast University, Nanjing, China, in 2022, under the supervision of Dr. Guyue Li. From April 2021 to September 2021, I worked as a Research Assistant with the Department of Computing, The Hong Kong Polytechnic University, under the supervision of Prof. Bin Xiao.

Feel free to drop me an email if you want to collaborate or have a discussion!
