Hadronic resonances can play a pivotal role in providing experimental evidence for partial chiral symmetry restoration in the deconfined quark-gluon phase produced at RHIC and the LHC. Their lifetimes, which are comparable to the lifetime of the fireball, make them a valuable tool to study medium modifications to the resonant state due to the chiral phase transition signatures of mass shifts and/or width broadenings. This can be done via the leptonic decay of resonances, however hadronic regeneration of resonances feeds into this signature as well. We will present the measurement of phi(1020) at mid-rapidity in p+p collisions and the preliminary results of the resonance signal in Au+Au collisions at 200 GeV using the STAR upgrade Time of Flight detector for electron identification.
