My current research interest mainly focuses on gravitational wave astrophysics, with strong connection to gravitational wave observations. There are two main themes: 1. Strong-field gravitational astrophysics. The objectives are to unravel physics buried within the data, provide new insights to guide observations and propose methods to improve data quality. Part of my research projects are related to the dynamics of compact binary and triple (neutron stars and black holes) systems, as well as their associated gravitational-wave emissions. I am also studying electromagnetic counterparts of binary neutron stars or neutron star-black hole mergers, in relation to future multi-messenger observations. 2.Fundamental physics with strongly gravitating systems. The goals are to examine dynamical signatures of modified theories of gravity and develop methods to measure or constrain violationsof General Relativity based on observed gravitational-wave data. As more and more detections are expected in the next a few years, there are unprecedented opportunities to search for "unknown unknowns" in fundamental physics with gravitational waves.
