• I was born and grew up in China. I received my B.A. in geography from Peking University, China, a master in GIS and remote sensing application from the Institute of Remote Sensing Application, Chinese Academic of Science. I got my Ph.D. in Geography from the joint doctoral program of San Diego State University and University of California at Santa Barbara in 2001. I had worked in ESRI as a GIS product specialist for one year before I came to Queen's University in 2002.

Research Interests

My research areas focus on the understanding and modeling of interactions between human activities and the physical environment by using GIS and remote sensing techniques and spatial modeling approaches from local to regional scales.

My current research interests include:

• Land use/cover change detection and modeling from time series remotely sensed images
• Machine learning and AI-based methods in GIS and remote sensing
• Spatial data privacy, error and accuracy
• Spatial-temporal disease risk analysis and modeling
• Analyzing environmental, ecological and health impact of urbanization and climate change
• Air pollution monitoring
