J/psi production is considered to be a sensitive probe of the properties of quark gluon plasma created in nucleus+nucleus collisions at RHIC. In this article, the recent analysis of mid-rapidity (|y| < 1) J/psi production via the dielectron decay channel in Au+Au (year 2007) and Cu+Cu (year 2005) collisions at sqrt(sNN) = 200 GeV at STAR is reported. It is compared to STAR p+p results in order to study the nuclear modification factor as a function of transverse momentum and centrality. The results are compared to previously published data and available theoretical models.
