I am a postdoc at the Berkeley Lab (LBNL). I got my PhD at University of California Santa Cruz (UCSC) with Prof. Alexie Leauthaud on galaxy formation and observational cosmology in 2024.
My research interests focus on the co-evolution between galaxy and dark matter, and the link between galaxy structure and the quenching process. My PhD thesis focused on building a new medium-band imaging survey "Merian Survey" which we will use 64 full nights on the Dark Energy Camera (DECam) to build a sample of 100,000 dwarf galaxies at z~0.1 for weak lensing, and enable us to constrain the dark matter halo properties via weak gravitational lensing for the first time. It can also constrain feedback physics by mapping out the properties of dwarf galaxies. At Berkeley Lab I work on a range of topics from observational cosmology to galaxy evolution. I serve as the run manager for the DESI Legacy Imaging Surveys DR11, which covers >30,000 square degrees of the sky in 4 bands (g, r, i, z) down to ~24 mag. I am also deeply involved with the Intermediate-Band Imaging Survey (IBIS), a new medium-band imaging survey using >260 dark nights on DECam (2024-2028). IBIS will be used to select galaxies at z>2 for DESI-2, as well as dwarf galaxies at z<0.4. The high efficiency of medium-band selection with IBIS will enable constraints on inflation and dark energy through measurements of large-scale structure at z>2, and on dark matter models via gravitational lensing around dwarf galaxies. I was born in Beijing, China. I became a stargazer during high school. Although I have been using professional large telescopes for several years, I still maintain my personal interest in astrophotography with small telescopes (I own a 5-inch APO refractor and a 6-inch Schmidt-Cassegrain reflector). I use my Canon 5D Mark III and Fuji X-T3 for photography in my spare time. On the left is a short video of the Milky Way that I took at Panoche Hills in California. All the photographs on this website are taken by myself. You may find more photographs here.
