|Research Area: Properties of galaxies and their environments|
I am an observational astrophysicist studying evolution of galaxies, and the symbiotic relationship between galaxy properties and the large-scale structure of the Universe in which they reside. Just like human behaviour is influenced by their social surroundings, properties of galaxies are influenced by their surrounding ``environment". My research interest lies in exploring and quantifying correlations between physical properties of galaxies such as colour, mass, morphology, dust content, star formation and metallicity to the properties of the environment: how clustered are the surroundings? Is the surrounding structure a group, a cluster or filament? I am also interested in studying dwarf galaxies. These galaxies are typically less massive and less luminous than an average galaxy found in the nearby Universe, and tend to show properties somewhat different from their larger counterparts.
For my research I have exploited arsenal of multi-wavelength data that are now available for millions of galaxies. I have also tested how the global star formation rates determined using data in ultraviolet, optical, far-infrared, and, radio wavebands compare with each other for a set of nearby galaxies. These metrics can then be used as a baseline for calibrating star formation rate for higher redshift galaxies for which multi-wavelength data seldom exist.
