I am research fellow at the SYmmetric cryptography and machine Learning Lab (SyLLab) in Nanyang Technological University since February 2025.

Previously,I got the PhD degree at the School of Cyber Engineering, Xidian University in China. My research interests focus on Symmetric-key Cryptography, Artificial Intelligence and Cryptanalysis. With the support of the China Scholarship Council, I received a joint training at Nanyang Technological University, Singapore for two years.
