Black hole astrophysics: Investigating the physical processes around black holes such as the dynamics and radiation of black hole accretion flows, jet, and wind. Active galactic nuclei (AGN) and black hole X-ray binaries are two main classes of black hole sources and are our main research targets to investigate. These studies can also help us to understand and develop general relativity.

Galaxy formation and evolution: Employing numerical simulations and observations to unravel the mysteries of galaxy formation, with a special emphasis on the roles of active galactic nuclei and cosmic ray in affecting star formation. Examining the properties and importance of the circum-galactic medium (CGM) the life cycle of galaxies is especially valuable to provide insights into the intricate environmental interplay shaping and influencing the growth of galaxies.

Cosmology: Understanding early universe quantum effects and the imprints they leave on late-time cosmology. To this end, we have developed a comprehensive effective framework for calculating quantum fluctuations of fields, applicable to cosmological spacetimes. We aim to use this framework to explore non-standard quantum initial conditions and evolution during the early universe, specifically their roles in various late-time cosmological anomalies.

Computational astrophysics: Ultilizing high-performace computing, leveraging advanced multi-physics magnetohydrodynamic simulations to model the intricate details of black hole accretion processes and the evolution of galaxies over cosmic timescales. Nowadays numerical simulation has become a more and more important tool in theoretical astrophysical study.
