  The recent results on di-electron production in $p+p$ and Au+Au collisions at
$\sqrt{s_{_{NN}}} = 200$ GeV are presented. The cocktail simulations of
di-electrons from light and heavy flavor hadron decays are reported and
compared with data. The perspectives for di-lepton measurements in lower energy
Au+Au collisions and with future detector upgrades are discussed.
