Research Interests
I am currently working in the field of computational material science. I am particularly interested in 2 dimensional materials, such as graphene and transition metal chalcogenides, etc. We try to develop new efficient computational methods to better describe the band structures and band gaps for those low dimensional materials. We also develop efficient and more accurate methods to calculate the van der Waals interactions in those 2D materials. Moreover, we use many-body perturbation theory, such as GW and Bethe-Salpeter equation, to check our methods, and also use those methods to study optical properties of many technologically important 2D materials and systems.
