My name is Song Huang (黄崧). I am an Assistant Professor at the Department of Astronomy in Tsinghua University, China. My primary research interest is the observational study of galaxy evolution and galaxy-halo connection.
Most of my works take advantage of today’s multi-band imaging data, spectroscopic surveys, and hydrodynamic simulations to probe the structure assembly and star formation history of different classes of galaxies.
My recent works focus on both the most massive (elliptical galaxies) and most abundant (dwarf galaxies) galaxies in our universe.
With the help of weak gravitational lensing and statistical modeling techniques, I also aspire to deepen our understanding of galaxy-halo connection models and explore the applications of such models in observational cosmology.

I am a member of the Subaru Strategic Program (SSP) using the Hyper-Suprime Camera (HSC) on the 8.2-meter Subaru Telescope and the Merian Survey - an intermediate-band survey of the HSC footprint using the Dark Energy Camera (DECam). Currently, I am applying to become a member of the Dark Energy Spectroscopic Instrument (DESI) spectroscopic survey project. I am also involved in the development of MUltiplexed Survey Telescope (MUST) a new 6.5-meter telescope in China for the next-generation spectroscopic survey.
