We have studied perturbations of scalar and spinor field in the background of three-dimensional Godel black hole. The wave equations are shown to be exactly solvable in terms of hypergeometric functions. The quasinormal modes are analytically calculated by imposing the Dirichlet boundary condition at spatial infinity, which are shown to be of the same form in both cases. By considering the physical interpretation of quasinormal modes, we obtain the consistent transition frequencies from the quasinormal modes of scalar and spinor field. As an application of quasinormal modes, we have also investigated the area and entropy quantization of three-dimensional Godel black hole. By choosing the conserved mass of Godel black hole properly, the entropy spectrum are shown to be equally-spaced.
