Research Topics (My Google Scholar Profile and Researchmap)

I am interested in algorithmic number theory and post-quantum cryptography, especially improving lattice algorithms and solving some hard mathematical lattice problems underlying lattice-based cryptography, i.e. the Shortest Vector Problem (SVP), the Learning With Errors (LWE) problem, etc. Recently, I have also focused on machine learning security, on the sides of both attack and defense.
