James W. Johnson studies how the Milky Way galaxy's chemical composition has evolved over cosmic time, using large surveys of stars to trace patterns of elements like carbon, nitrogen, and helium. This work, often called 'galactic chemical evolution' or 'galactic archaeology,' helps reconstruct the history of star formation and how different parts of the galaxy formed and merged. Prospective students would likely work with large public datasets from sky surveys such as SDSS and APOGEE, combining observational data analysis with modeling of stellar processes.
