Neutrino oscillations, and in particular muon neutrino disappearance, have been verified several times and with increasing precision. However to paint a complete picture of neutrino oscillations it is also essential to measure tau neutrino appearance at a very precise level and evaluate the unitarity of the mixing matrix. Recent improvements in the precision of the DeepCore measurement of muon neutrino disappearance were mainly possible due to improvements in reconstruction algorithms and in the efficiency of event selection. In addition to the improved precision for muon neutrino disappearance, these improvements have also opened the possibility of making a statistically significant measurement of tau appearance around the first oscillation maximum at 25 GeV, using the high statistics neutrino sample available. In this presentation we discuss the current progress towards this measurement using DeepCore.
