Abstract : Dust plays an important role in all formatory and evolutionary processes of galaxies. Accounting for its presence is critical to compute the accurate star formation rate of the galaxies. Dust mass has been found to be correlated with the amount of neutral gas, molecular gas & metallicity in galaxies. It is also dependent on the star formation history and dominant star formation mode in galaxies. In addition to reviewing the status of our understanding of the presence and effects of dust in galaxies, I will give an overview of the efforts my group is making to further our insight. We are computing the structural parameters of a statistically large sample (~16,000) of local galaxies in the infrared (Ks) band. For these galaxies, high-resolution multiwavelength photometric & spectroscopic data is available, in addition to latest & most accurate stellar & dust parameters. Our aim is to draw a detailed comparison of the properties of "dusty" & "non-dusty" galaxies. This will enable us to set benchmark local relations, which should act as a crucial resource for future studies.
