Research Interests

My recent research interests are mainly in the fields of

  • Observational cosmology
  • Galaxy formation
  • Gravitational lensing
  • Cosmological numerical simulations
  • QSO absorption line systems

In the field of simulations, I finished a set of cosmological N-Body/SPH simulations using Gadget-2 at Shanghai Supercomputer Center and have published over 15 SCI papers using the data, particularly focusing on the influence of baryon on the clustering and properties of dark matter halos, as well as the dynamical merging scale of galaxies. As we pointed out, in the epoch of presice cosmology (at an uncertainty level of several percentages), the baryon physics IS very important and should be considered and corrected carefully. I am also a core member of the Chinese Computational Cosmology Consortium (C4) and ELUCID project (Exploring the Local Universe with re-Constructed Initial Density field from SDSS).

In the field of observations, I take part in several large surveys, including SDSS-IV (Sloan Digital Sky Survey-IV, full member), Go-IRS (the GTC Optical Intermediate Resolution Spectrograph, science team member & survey scientist) and MS-DESI(BigBOSS) (The DOE-NSF Stage IV ground-based dark energy experiment to survey baryon acoustic oscillations). I am also intersting in the construction and science studies of TMT (the Thirty Meter Telescope).

I also keep an eye on high energy astrophysics and other fields even though I haven't made contributions yet. But I hope to get involved in near future.
