Discoveries over the past half-century have put neutrinos in the spotlight for further research into fundamental questions about the nature of matter and the evolution of the universe. The Deep Underground Neutrino Experiment (DUNE) at Fermilab is a worldwide leading next-generation neutrino experiment that will seek to answer some of these questions. I will introduce neutrino oscillations and the current results and the recent developments in DUNE with a particular focus on the Near Detector Complex.
