My main interest is galaxy formation and evolution seen through the study of discrete tracers. At large distances or at large galactocentric radii, where the stellar component of galaxies is too faint to measure, discrete tracers such as globular clusters and planetary nebulae are excellent tools for unveiling the properties of the underlying stellar population.
