Star Formation Histories from synthetic CMDs
The most widely used method to infer SFH of
resolved galaxie was invented here
Tosi et al. 1991
5
Spatially resolved SFH in the local Universe
Deep, high-res photometry allows to resolve
stellar populations and derive CMDs. From them,
the method provides SF history and IMF.

Models of chemical evolution in galaxies
The key interpretative tool for the observations
of the chemical enrichment
An example primordial nucleosynthesis The
predictions of our models on Deuterium verified
by WMAP
Comparisons of this kind will soon be possible
also in nearby external galaxies (UVES-Flames)
