Outstanding Researcher Award. 2007. Columbia-Willamette
Chapter of Sigma Xi
Best Poster Award. 2006. International Water Association
My teaching and research interests lie in hydrology and spatial analysis. In hydrology and water resources, I am interested in examining the human modification of the hydrologic system. I examine the complex interactions among climate change, land use change, and water management that drive major changes in water quantity and quality. To understand and model such a complex system, I use an integrated approach that embraces biophysical sciences, social sciences, and information sciences. Hence the use of geographic information technology including geocomputational methods and visual spatial analysis is essential to conduct my research and teaching.
