Main interests: Resolved stellar systems - parameters of cosmological interest. Development of the photometric package, ROMAFOT, to deal with poorly sampled images. Accurate photometry to constrain the input physics for evolutionary models and to provide accurate estimates of the ages of globular clusters. Star counts as gauge of fast evolutionary phases. Primordial He content in old stellar systems. Detection of (relatively) young globular clusters in the Milky Way. Globulars in Fornax dwarf galaxy Stellar populations in Local Group dwarf galaxies. Stroemgren photometry of globular clusters.
