NOvA is a two detector, long-baseline neutrino oscillation experiment designed to study nue (nue bar) appearance and numu(numu bar) disappearance in a numu(numu bar) beam produced at Fermilab. The near detector (ND) is located 100 meters underground at a distance of 1 km from the target whereas the far detector (FD) is located on the surface, 810 km away from the beam source in Ash River, MN. In this talk I will present the technique of extracting neutrino oscillation parameters using a simultaneous fit of the nue appearance and numu disappearance neutrino and anti-neutrino data in the NOvA experiment.
