Chengcheng received her Ph.D. in Astronomy from Columbia University in 2025. Her research focuses on multimessager signatures of compact binary supermassive black holes, their observation in time-domain surveys such as LSST and the Nancy Roman Telescope, and their detectability as low-frequency gravitational waves in LISA/PTAs. Additionally, she is recently interested in the physics of stellar-mass black holes and their interactions with stars in the galactic center.
