Neutral hydrogen (HI) studies are important for understanding galaxy evolution since HI is the primary ingredient essential for star formation. HI morphology can tell us a lot about a galaxy’s environment and whether it has likely to have undergone any interaction or merger, and as such the project will also involve parametrising the HI morphologies of galaxies. One of the main goals of my PhD is to study the HI distribution as a function of stellar mass. A trend in the distribution of HI and stellar mass based on the different morphological and optical types would then lead to a distinction in the evolutionary stages of galaxies, thus paving ways to understanding their evolution. I will also examine if environmental effects influence the HI content in galaxies.
