I am the 2019 NASA Hubble Fellow (short bio) at Carnegie Observatories. Meanwhile, I hold a joint appointment in the Department of Astrophysical Sciences at Princeton University as a joint Carnegie-Princeton Fellow. I will join the Department of Astronomy and Astrophysics at the University of Toronto as an assistant professor in Summer 2021.
I was a Leon Lederman Fellow at the Fermilab Center for Particle Astrophysics during 2016-2019. Before joining Fermilab, I was a graduate student in the Department of Physics and Astronomy at Texas A&M University. I received the Eramus Mundus Scholarship for a Joint European Master in Space Science and Technology (SpaceMaster), during which I stayed in Germany, Sweden, France and Japan for 6 months each. I completed my undergraduate at Fudan University in Shanghai, China, with a major in Physics and a minor in Diplomacy.
I'm an observational astrophysicist, mostly working on near-field cosmology, Galactic archaeology, and metal-poor stars. My main interest is to study the Milky Way halo and use that to understand the formation history of the Milky Way and the nature of dark matter. In particular, I search for interesting substructures in our local Universe, including stellar streams and dwarf galaxies, with modern imaging surveys such as the Dark Energy Survey (DES). After finding them, I also follow up the stars in the streams and galaxies to study their kinematic and chemical properties, using large optical telescopes all over the world. In Summer 2018, I initiated the Southern Stellar Stream Spectroscopic Survey, or S5, to map the kinematics and chemistry of stellar streams in the Southern Hemisphere. I am also currently one of the co-chairs of the DES Milky Way Working Group.
Apart from the science interest, I am also an instrument builder. During my postdoc, I am actively involved in the Dark Energy Spectroscopic Instrument (DESI) Survey. In particular, I am building the focus and alignment system for DESI, which is an essential component for the survey commissioning and operation. In my graduate school, I worked in the Munnerlyn Astronomical Instrumentation Lab, where I helped design and built the auxiliary calibration systems, namely aTmCam and DECal, for DES, which are used to improve the precision of the photometric calibration to better than 1%. I have also worked on a few other instrumentation projects, such as the Giant Magellan Telescope and the HETDEX project, etc.
