I am an Associate Professor at the Department of Earth System Science, Tsinghua University. My research has used geographical information techniques to monitor and model global land-use change, especially cropland and to facilitate many applications, e.g., food security, biodiversity conservation, and land-system modelling. I particularly focus on satellite-based methods to quantify the spatiotemporal change of land cover/use and understand their ecological, environmental, and socioeconomic impacts on sustainable development and increasingly on the forestry sector. I am a Fellow of the Royal Geographical Society (RGS-IBG), Fellow of the Higher Education Academy, Senior Member of the Institute of Electrical and Electronics Engineers, and Prominent Visiting Researcher at the University of Technology Malaysia (UTM). I am currently Editor-in-Chief of Geo: Geography and Environment, Section Editor-in-Chief of LAND, Associate Editor of International Journal of Remote Sensing, and editorial board member of Global Sustainability, Scientific Data and Geoscientific Model Development.
