About Me
I am an Assistant Professor in the Department of Convergence Security Engineering at Sungshin Women’s University. Before joining Sungshin Women’s University, I was a research staff member at Samsung SDS from 2020 to 2024. I received Ph.D degree in Mathematical Sciences at Seoul National University, under the supervision of Prof. Jung Hee Cheon My research interests includes privacy enhancing technologies (PET) for secure comptuation, especially homomorphic encryption or multi-party computation, and concrete security of lattice-based cryptographic hard problems.
