Probing the Cosmic Reionization History and the Earliest SMBHs Using Distant Quasars
As the most luminous non-transit objects, quasars are unique probes of the early Universe. I have been leading a wide-field reionization-era quasar survey, which has provided the first large statistic...

Stochastic gravitational waves from Primordial Black Holes
The discovery of gravitational waves from the coalescence of binary black holes in 2015 has marked the dawn of the gravitational wave (GW) astronomy/cosmology. Besides the gravitational wave bursts fr...

Modeling Signals from Star--Compact-object Binaries
Precision radial velocity and photometric monitoring of a large number of stars may reveal hitherto overlooked populations of binary systems consisting of normal stars and unseen compact objects. I wi...
