The Reactor Experiment for Neutrino Oscillation (RENO) has been taking data from August, 2011 using the two identical near and far detectors at Hanbit Nuclear Power Plant in Korea. The neutrino mixing angle θ13 and the squared mass difference Δm2ee have been successfully measured by observing the energy dependent disappearance of reactor antineutrinos tagged by neutron capture by gadolinium. In this talk, we present improved results of θ13 and Δm2ee measurements and the first measured value of θ13 using neutron capture on hydrogen. We also report results on the evolution of reactor antineutrino flux and a search for light sterile neutrino mixing.
