My research interest lies in the accretion of compact objects of various scales, e.g., black hole/neutron star X-ray binaries, active galactic nuclei, and tidal disruption events.

The main focus of my theoretical research is modeling the accretion of black holes by investigating the energy coupling and matter exchange between the accretion disk and the corona (i.e. the evaporation of the disk and the condensation of the corona), under the supervision of Prof. Bifang Liu at NAOC. Most recently we investigated the possible condensation of the hot flow and hence the formation of an inner disk in the low/hard state of black hole X-ray binaries.

As an associate member of the Einstein Probe Science Topical Panel 4, I have been working as a transient advocate for the Einstein Probe and its path-finder, Lobster Eye Imager for Astronomy (LEIA), from which I have gained basic knowledge in observation and X-ray data analysis.

Starting from February 2025, I am a visiting PhD student at the Institute of Space Sciences (ICE, CSIC-IEEC) in Barcelona. Under the supervision of Prof. Nanda Rea, I study the activities of low-mass X-ray binaries utilizing the Einstein Probe data.
