Welcome
I am an associate research fellow in the Department of Astronomy at the University of Science and Technology of China (USTC). I study active galactic nuclei, star-forming galaxies, and massive black holes.
My studies leverage multi-wavelength data to investigate AGN-related physics, such as black hole measurement, the co-evolution of black holes and their host galaxies, and AGN feedback.
