We consider the nu(mu)-> nu(tau) appearance channel in the future Deep Underground Neutrino Experiment (DUNE) which offers a good statistics of the nu(tau) sample. In order to measure its impact on constraining the oscillation parameters, we consider several assumptions on the efficiency for nu(tau) charged-current signal events (with subsequent tau -> e decay) and the related backgrounds and study the effects of various systematic uncertainties. Two different neutrino fluxes have been considered, namely a CP-violation optimized flux and a nu(tau) optimized flux. Our results show that the addition of the nu(mu)-> nu(tau) appearance channel does not reduce the current uncertainties on the standard 3-nu oscillation parameters while it can improve in a significant way the sensitivity to the Non-Standard Interaction parameter |is an element of(mu tau)| and to the new mixing angle theta(34) of a sterile neutrino model of the 3 + 1 type.
