Abstract

Feedback from massive stars in the form of stellar winds, ionizing radiation, and Supernova explosions shapes the structure and dynamics of the multi-phase interstellar medium. Here, I will briefly summarise some of our recent studies and findings on these subjects. I will discuss the effects of ionizing radiation and stellar winds in individual molecular clouds. Furthermore, I will shortly introduce the SILCC project, in which we model the evolution of the Supernova- and wind-driven, multi-phase ISM in stratified galactic discs.
