Andrea is a support scientist at the Institute. His functional duties are split between the ACS and the Nancy Grace Roman Space Telescope teams. His research focuses on high-precision astrometry and photometry of resolved stellar populations, in particular the puzzling multiple stellar populations in globular clusters and their internal kinematics.
- Multiple stellar populations in globular clusters
- High-precision proper motions and internal kinematics of stellar systems
- Globular cluster formation and evolution
- Cluster dynamics
Research Topics: Resolved Stellar Populations, Globular Clusters, Open Clusters, Proper Motions, White Dwarfs
