The evolution and formation of dwarf galaxies has great importance to our knowledge of cosmological history from the Big Bang through the present day structure we observe in our local universe. Dwarf galaxies are believed to be the ''building blocks'' of larger galaxies, which implies that interactions and mergers of these small systems must have occurred frequently in the early universe. There is a population of starburst dwarf irregular (dIm) galaxies that seem to have characteristics indicative of interactions or mergers. One of these dIm galaxies is the nearby post-starburst NGC 1569. We explore the stellar and gas kinematics of NGC 1569 as well as examine a deep HI map made using the Robert C. Byrd Green Bank Telescope (GBT). From these observations, we analyze the evolution of NGC 1569 by understanding the three-dimensional shape of this dIm system. The structure of dIm galaxies is an important fundamental, physical property necessary to understand the evolution and formation of these common systems.
