I am trained as a fluvial geomorphologist specialized in sediment transport. My current research centers on watershed sediment transport and GIS-based spatial analysis. I am interested in understanding dynamics of sediment transport across multiple spatial scales through field monitoring, computer modeling, and statistical analysis. Amassed research results (including mine) suggest that sediment dynamics may be efficiently characterized at the event time scale. Based on this finding, I am investigating the complexity of watershed sediment dynamics using the framework of connectivity. I am developing an approach of revealing sediment connectivity over multiple spatial scales using both field monitoring and computer simulating in terms of physically based watershed models: Dynamic Watershed Simulation Model (DWSM) and Model for Assessing Hillslope-Landscape Erosion, Runoff And Nutrients (MAHLERAN). Examples of on-going research are (1) the general relationship between event sediment yield and runoff depth in watersheds with different sizes and under variable climatic conditions, and its geomorphological implications; and (2) quantitative relationships among event sediment yields from small upland sub-watersheds to the entire watershed.
I am also actively involved in studying the interaction between human dwellings and their environments using GIS techniques. This type of research is primarily focusing on green building/environment design across multiple spatial scales within a city. Examples of active research projects are (1) generating the 3D GIS model of a neighborhood in City of Syracuse using LIDAR data for air pollution simulation and dynamic visualization; and (2) Designing low-carbon neighborhood using CityEngine.
