Jay's research is centered in two areas. The first is near-field cosmology with massive globular clusters: using the stellar populations and kinematics of clusters to constrain the formation and assembly histories of nearby galaxies, with a focus on their outer halos. He also studies the properties of globular clusters themselves, including the presence of black holes, multiple stellar populations, and stellar winds from red giants.
