Precise determination of the neutrino mixing angle $\theta_{13}$ is important for searches of CP violation in the lepton sector. The Daya Bay Reactor Neutrino Experiment (Daya Bay) observed electron antineutrino disappearance and measured a nonzero value of $\theta_{13}$ with a significance greater than 5 standard deviations in early 2012. With the final two detectors installed, Daya Bay resumed recording data in its full 8-detector configuration in late 2012. More than 1,000,000 (150,000) electron antineutrino candidates had been collected with the near (far) site detectors by the end of 2013, significantly improving the precision of the $\theta_{13}$ measurement. In addition to the precise determination of $\theta_{13}$, Daya Bay is also capable of exploring other neutrino research. In this talk, I will present our recent progress in the measurement of neutrino oscillation parameters $\sin^2 2\theta_{13}$ and |$\Delta m^2_{ee}$| using neutron capture on gadolinium, the measurement of $\sin^2 2\theta_{13}$ using neutron capture on hydrogen, the search for a light sterile neutrino, and the measurement of the reactor neutrino flux and spectrum.
