Despite the great developments that have been achieved in the last decade in disentangling most relevant stellar population parameters, in particular with the inclusion of absorption linestrength indices, the age-metallicity degeneracy still lurks in these studies. Here I summarize our effort for developing the stellar population synthesis method

Observations show a relation between the brightest young star cluster and the present overall star formation rate of a galaxy. A possible explanation would be the formation of complete cluster populations in rather short formation epochs lasting ≈ 10 Myr. This implies that the star formation history of a galaxy is a sequence of formation epochs, in

Motivated by recent progress in the study of early-type galaxies owing to technological advances, the launch of new space telescopes, and large ground-based surveys, we attempt a short review of our current understanding of the recent star formation activity in such intriguing galactic systems.

We present the observational properties of the dwarf galaxy population (Mr>M*r+1) corresponding to one of the largest samples of spectroscopically confirmed nearby galaxy cluster members reported in the literature. We have observed that red dwarf galaxies (u-r>2.22) share the same cluster environment as the brightest cluster members (Mr
