I am a graduate student studying astrophysics at Harvard University. I am interested in understanding the chemical enrichment/dynamical history of the Milky Way. Understanding the formation and evolution of the Milky Way galaxy is a fundamental unsolved problem in astrophysics. Our Galaxy offers by far the best chance to study a galactic system in great detail and hence to learn as much as possible regarding the formation of its structural components (disk, bulge, and halo) and also, on a smaller scale, how gas is converted to stars and how stars migrate around and within the Galaxy. A basic question is how stars form, at what rates, and in what types of aggregates. This can be observed directly only at present time. In order to understand what happened in the Milky Way at earlier epochs, we must study the fossil record.
My main research involves unraveling the fossil record of star formation in the Milky Way through the study of elemental abundances of stars in a global scale. This will shed light on how stars form, in particular, the extent to which stars form in small or massive clusters of stars. Detecting the most massive clusters in the fossil record would not only shed light on how stars form but would also provide novel insight into the evolution of the gravitational potential of the Milky Way as it is the latter that sets the maximum fragmentation mass in galactic system.
Besides my main research, I am also involved in the study of nearby extragalactic evolution. We study about 500 early-type galaxies with prominent dust lanes. These galaxies have gone through recent minor mergers and are prototypes in the understanding of star formation at present time. On top of that, I am also interested in massive online open courses (MOOC) and developing interactive tools to teach physical science.
