Title:  Star clusters as footprints of star formation, stellar feedback 
and assembly history of galaxies

Abstract:
Star clusters are gravitationally bound stellar systems commonly formed 
in star formation events. These systems form in the densest regions of 
giant molecular clouds and host the majority of the massive stars 
forming in these regions. A quick look at the cluster population in our 
Milky Way already proves that these bound stellar systems have 
continuously formed during the assembly history of our own galaxy, as 
witnessed by globular clusters, open clusters, young star clusters. I 
will present some key results that relates the most recent efforts to 
link the statistical properties of cluster populations in local galaxies 
(i.e. mass functions, dissolution time scales, formation efficiency) to 
the global physical properties of galaxies, such has star formation per 
unit area, gas surface density,  and dynamics. I will show how key 
events for galaxy evolution, such as mergers or increased gas fraction 
change the properties of the stellar clusters formed during these 
enhanced star formation events, therefore making them tracers of the 
assembly history of galaxies. I will conclude presenting some 
preliminary results about the effect of cluster feedback on their 
immediate surroundings and at galactic scales showing that star clusters 
are fundamental components of the star formation cycle of galaxies.
