My research focuses on Cryptography at the intersection of Mathematics and Computer Science — particularly how algebraic and geometric structures arise in cryptographic systems. I work on both the theoretical foundations and the practical implementation of secure cryptography, connecting rigorous mathematical analysis with real-world applications.
