The DZero Experiment is one of two large collider detectors located at the Fermi National Accelerator Laboratory near Chicago, Illinois. The detector has been designed to efficiently identify leptons and jets, including the tau lepton. Due to its large mass at 1.78 GeV, the tau decays prior to reaching any detector and distinguishing them from different backgrounds requires effective identification algorithms. These include multivariate techniques such as neural networks. Methods used to identify tau leptons produced in high energy ppbar collisions at the Tevatron are presented as well as the procedures used to discriminate against background particles misidentified as taus. The discussion also focuses on several physics results obtained by applying these methods, using up to the 1 fb-1 of integrated luminosity delivered by the Tevatron. In particular, measurements of tau final states from W and Z boson production, Higgs, and SUSY are described.
