Experience

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