Research Interests
My research interest lies in both the applications and algorithms of first-principles computational methods. Currently, I am particularly interested in understanding and solving physical problems in solids and liquids by exploring the locality of Wanniers orbitals. These problems include: 1. The inverse design of superlattices with desired multifunctionalities. 2. The developments and applications of order-N exact exchange based functionals (PBE0 hybrid functional, GW quasi-particle approximation, etc.).
