BS in Astronomy, Beijing Normal University, 2020

Research Interests

Planetary Climates , Exoplanet Atmospheric Evolution, Orbital evolution: I am interested
in how the formation history and orbital evolution of exoplanets shape their potential habitability. My current research focuses on: (1) how planetary climates respond to varying orbital configurations, and (2) how atmospheres are gained, lost, or retained. My long-term goal as a researcher is to identify which types of planetary system architectures are most likely to produce and sustain habitable planets.
