I am a fluvial geomorphologist specialized in sediment transport. My current research centers on understanding hydrological, erosional, and sediment-transport processes shaping river environments under the influence of climate change and human activities in the source regions of Yellow and Yangtze Rivers, China. Located in the world’s highest plateau, Qinghai-Tibet Plateau, rivers and their contributing lands, often featured by glaciers and high mountains covered by snow, store a large amount of fresh water and form a diverse, but fragile ecosystem that has been disturbed by climate change and human activities. My current research primarily involves three specific directions: (1) morphodynamic characteristics of meandering river clusters in the source region of the Yellow River; (2) hydrological and erosion processes of peatland in the Zoige Basin; and (3) dynamic changes of morphological structures of braided river clusters in the source region of the Yangtze River. This research, which is under way in collaboration with Dr. Zhiwei Li from Changsha University of Science & Technology, China, takes process-based approaches to quantifying complex physical processes and the associated morphologic responses of rivers and uplands using a variety of methods including field observation/measurement, photogrammetry (e.g., drone data) and GIS analysis, laboratory experiments, and model simulation.
I am also actively involved in studying the impact of microclimate (e.g., rainfall, solar radiation) on urban environments and forms using GIS techniques and model simulation.
