Research Interests

The main focus of my research is in theoretical high-energy astrophysics to investigate the physical mechanism of black holes: accretion disks and relativistic physics in the vicinity of black holes as well as their large-scale influence on hot intracluster plasma and cosmic feedback from supermassive black holes.
