**Abstract**: In this talk, we present several applications of the sparse grid discontinuous Galerkin (SGDG) schemes. The SGDG scheme was first proposed by Cheng [1] for high-dimensional elliptic equations for tackling the curse of dimensionality. In this talk, we will first review the scheme's construction and then design the corresponding numerical schemes to solve several partial differential equations in the computational plasma physics field, including Maxwell, Vlasov, Fokker-Planck equations. Besides, we also discuss several extensions to the sparse-grid schemes.
