I am interested in studying the formation and evolution of galaxies using primarily observational techniques. My recent work focuses on the effect of the local environment of galaxies on their star-formation activity and using satellite galaxies to test the nature of dark matter and feedback mechanisms in galaxy evolution.
My research utilizes the data from two of the NASA's space-based Great Observatories (Hubble and Spitzer) and the terrestrial telescopes, including Magellan Telescope, the Blanco 4-m telescope at CTIO. I am involved in multiple international collaborations, including the ZFOURGE, CANDELS, and HETDEX projects.
At Kavli IPMU, I take a further step by utilizing the Subaru Hyper-Suprime Cam survey (and the Subaru Prime Focus Spectrograph in the near future) to measure the build-up of massive quiescent galaxies (those lacking substantial star formation) across the full range of environments (cluster, group, and field galaxies). My goal is to separate the effects of processes associated with halo mass from those associated with the large-scale environment on the suppression of galaxy star formation.
