About Me


I am an assistant professor in the Department of Astronomy at Tsinghua University, Beijing, China.

I work on the detection and characterization of exoplanets using precise radial velocities (RVs). My current research focuses on improving the RV precision, through:

  • better understanding of stellar activity and jitter (PI for the RVxK2 and RVxTESS projects);
  • better ensembles for population studies of small planets (co-leader for the Magellan TESS Survey, led by Dr. Johanna Teske at Carnegie).
  • better treatment of telluric contamination (team lead for the EarthFinder tellurics study);
  • better data analysis techniques (team member of NEID and MINERVA).
