About Me
I am an Assistant Professor at the Department of Geography and Resource Management, The Chinese University of Hong Kong (CUHK). 
My research addresses the interactions between human activities and the environment by developing innovative geospatial analytical methods. I strive to address the issues of the impact of the environment on human health through the lens of movement flows, transportation related emissions and traffic congestion, and built environment. My research primarily relies on large movement datasets (e.g., GPS trajectories), together with a variety of other data sources including individual GPS tracking, mobile sensing, remote sensing, land use, built environment and activity travel diaries (My CV).
