- Study
accretion process around black holes across mass scale: from
stellar-mass black holes in X-ray binaries to supermassive black
holes in galactic nuclei
- Search
for tidal disruption events (tidal disruption of stars
by otherwise dormant supermassive black holes)
- Search
for intermediate-mass black holes of mass 100--100,000 solar mass
- Study
large surveys/catalogs

-
Investigate
the outbursting supermassive black holes at the center of galaxies,
especially their tidal disruption of stars
-
Search
for distant off-nuclear intermediate-massive black holes so as to
identify the remnants of massive population III stars in the early
Universe or tidal stripping of merging satellite dwarf galaxies
containing nuclear black holes
-
Study
the properties of X-ray binaries in NGC 3115 using the Chandra
extremely deep observations of this galaxy
-
Study
the X-ray counterparts to Fermi unidentified GeV sources
-
Improve
the unified model for neutron star low-mass X-ray binaries

-
XMM-Newton
data screener, screening the real-time XMM-Newton data product and
producing the quality report
- Member
of XMM-Newton Science Analysis Software Developing Working Group,
including daily compiling and testing of the software
- Systematic
classification of point sources in the XMM-Newton X-ray
Serendipitous Source Catalogue, studying the long-term and
short-term X-ray variability for different classes, correlating with
other wavelengths, optimizing the criteria to differentiate
different classes, and searching for new interesting X-ray sources
with significant scientific values, such as cooling neutron stars
and new X-ray transients.
- Studying
X-ray binaries using XMM-Newton data in combinations with other
X-ray instruments.

Investigate
the accretion process in the neutron-star low-mass X-ray binaries
using data from many X-ray instruments, including RXTE, Chandra,
XMM-Newton, Suzaku, Swift and BeppoSAX.
- Scrutinize
RXTE/ASM weekly all-sky maps to detect new X-ray transients.
- Develop
a new solution to the decades-old problem of spectral modeling of
the accreting neutron stars.
- Analyze
the transient neutron-star binary XTE J1701-462 to find the direct
global relation among different types of accreting neutron stars and
the causes of the spectral evolution at high accretion rates.
- Develop
software for the Fourier frequency resolved spectroscopy.

Work
on two-fluid non-axisymmetric MHD numerical simulation of the solar
wind evolving from the sun to the earth.
- Quantify
the angular momentum in the solar wind and investigated how it transports
in the non-axisymmetric case.
