About Me

I am currently as a Full Professor at Astronomy Department, Beijing Normal University. I work on CMB physics, Large-scale Struture formation and astrophysical originated gravitational waves. In details, it covers Dark Energy/Modified Gravity, Weak Lensing, Strong Lensing, parameter estimation, non-gaussianity and higher-order statistics etc. I am memeber of the J-PAS Consortium, AliCPT project and CSST collaboration.

Area


Dark Energy On the linear regime of the density perturbation, we use the Effective Field Theory approach; on the mildly non-linear regime, we are interested in the extension of Lagrangian Perturbation Theory; on the extremely non-linear regime, we are interested in the N-body simulation algorithm and corresponding halo model.



Gravitational Lensing We are interested in CMB Lensing, galaxy Weak Lensing, Strong Lensing. In particular, delensing operation for the measurement of CMB B-mode polarization.

Gravitational Waves We are interested in several aspects of the astrophysical sources of the gravitational wave, such as gravity test in the strong field regime; Strong lensing; galaxy-black hole co-evolution; precision cosmology w. standard sires, etc.



Besides these, we are also interested in, Higher order statistics, Cosmic inflation mechanism, etc.
