There has been significant interest in the possible effect that one or more light sterile neutrinos, hinted by several short-baseline neutrino oscillation experiments, can have on the measurement of the three-neutrino mixing parameters at the future long-baseline Deep Underground Neutrino Experiment (DUNE), with a particular focus on their effect on CP-violation measurements. By the time DUNE is operational, however, the Short-Baseline Neutrino (SBN) program at Fermilab will have performed high-precision measurements of possible light sterile neutrino oscillations, or will have provided stringent constraints to such scenarios. In this work we will present results on a joint SBN+DUNE light sterile neutrino oscillation analysis, combining both $\nu_{e}$ appearance and $\nu_{\mu}$ disappearance oscillation measurements at both long and short baselines. By utilizing a fast MonteCarlo simulation of all SBN and DUNE detectors, we estimate the effects that either a positive or a null observation at SBN could have on DUNE sensitivities.
