Professor Tang is a geographer who uses remote sensing and spatial analysis to study the changes to the Earth’s surface with a focus on monitoring land use/land cover change and its impact on terrestrial carbon cycle and forest ecosystems.

He specifically interested in developing new methods for monitoring changes at regional to global scales using time series analysis and multi-sensor data fusion, and the use of spatiotemporal modeling to reduce the uncertainties in estimates of carbon emissions.

Tang is exploring new research ideas on the social and economic impact of human-driven changes to the Earth’s surface and how that affects sustainability. His research takes advantage of the abundance of freely available high-quality remote sensing data and the advancement in cloud computing capacity.
