The Daya Bay Reactor Neutrino Experiment started taking data on Christmas Eve in 2011. Our first results were released in March 2012, demonstrating neutrino mixing between the first and third generations at the five sigma level. Data taking continues to this day, with various upgrades to the experiment having been implemented along the way. Over two million neutrino events have been collected and analyzed, giving precise results on the mixing angle and mass difference. Other results include a cross check using np capture, a search for "sterile neutrino" oscillations, and the observation of unexpected features in the reactor neutrino spectrum.
We will start with a review of neutrino oscillation phenomenology, followed by a brief technical description of the Daya Bay experiment. The talk will then focus on the results of our measurements, future plans for Daya Bay, and a discussion of the next phase of reactor neutrino oscillation experiments.
