Hi there! 😃

My name is Zhongying and I am a fifth-year PhD candidate in Geography at the University of Colorado Boulder, supervised by Prof. Morteza Karimzadeh at the GeoHAI Lab. My work lies at the intersection of AI and Geography (GeoAI). My research focuses on GeoAI methods for environmental health and public health applications. In particular, I work on high-resolution air pollution estimation using satellite, ground and simulation data; spatiotemporal deep learning and data fusion for geospatial prediction; and geospatial foundation models and pretrained location encoders.
