Abstract

This thesis is a multi-layer body of work that starts from investigating the processes governing the evolution of dust grains out to the influence of dust on the interstellar medium (ISM) and, consequently, on the galaxy evolution as a whole. This thesis constrained the value of the parameters that control dust evolution, established the crucial role of photoelectric heating (a dust-related process) in regulating the ISM properties, star formation, gas outflows and formation of disc clumps, and discovered that ram pressure redistributes/mixes the ISM of galaxies in clusters/groups. These accomplishments make an appreciable contribution to our knowledge of the mutual dust-ISM evolution and dust influences on galaxy evolution.
