Astronomers try to map out the mass build-up of galaxies over cosmic time. To do this, we must understand the key periods and phenomena that shape galaxies, their surroundings, and the Universe as we whole. My research interests fall under two broad categories: gas inflows and outflows that regulate the gas content, star formation, and metallicities in and around galaxies, and a period of the early Universe called the "Epoch of Reionization", when the first stars and galaxies formed.
To observe these galaxies and phenomena, astronomers require powerful telescopes to build up large samples with which to understand their properties. My research makes use of optical, near-infrared, sub-millimetre and radio data coming from several space- and ground-based telescopes (e.g., Hubble Space Telescope/WFC3, Spitzer Space Telescope/IRAC, Keck/MOSFIRE, VLT/X-Shooter, IRAM 30m, Arecibo). The majority of my work makes use of large dedicated surveys such as the SDSS DR7, SDSS-IV/MaNGA, xCOLD GASS, and ALFALFA.
