About
I am currently a Lecturer with the School of Computer Science and Cyberspace Security at Huaiyin Normal University. I received the Ph.D. degree at Nanjing University of Aeronautics and Astronautics (NUAA) in 2026 under the supervision of Prof. Çetin Kaya Koç.
My research interests mainly focus on homomorphic encryption, matrix computation, and machine learning.
