Xiaogang He is a Ph.D. candidate in the Civil and Environmental Engineering. His research interest focuses on the fundamental understanding of how climate change and climate variability affect the global flood and drought risk (FDR) and how we can improve the predictability of these extreme events to reduce their potential impact. Xiaogang has been developing a multi-scale physically motivated, information-theoretic framework to better quantify and diagnose changes in FDR in relation to climate variability and change, and anthropogenic influences such as water management (e.g., reservoir operations, irrigation, water withdraws). This framework can help to decouple the complex interaction mechanisms and identify key processes that drive the long-term changes in FDR across different spatial and temporal scales. In order to transfer science into action, Xiaogang is working on the development of an online operational Global Flood and Drought Monitor system with an objective of improving FDR management over the globe. This high-resolution (~25 km) system can provide information on historical, present and predicted/projected hydrological conditions at different time scales, which are important to many sectors, including water, agriculture and food security, energy production, infrastructure and ecosystem health. It also has ramifications for disaster preparedness and mitigation, policy making and political response to climate change.
