Currently I'm a Ph.D. student in Applied Mathematics at the Academy of Mathematics and Systems Science, Chinese Academy of Sciences. My research interests mainly lie in lattice-based cryptography, especially the lattice isomorphism problem. I am also interested in other directions in lattice-based cryptography, including classical and quantum algorithms for lattices and signature design.
