Both the strong CP problem and the mu problem of MSSM can be nicely resolved by realizing the supersymmetric DFSZ axion model. In this scheme, there are three candidates of dark matter: the usual neutralino, the axion and the axino which is a fermionic superpartner of the axion, and due to which dark matter cosmology and collider phenomenology of the usual neutralinos/charginos can alter significantly. In this lecture, we introduce the axion physics in supersymmetry and discuss various cosmological and phenomenological consequences of the DFSZ axino.
