Welcome to my website. I am Associate Professor of Watershed Hydrology Laboratory at the Natural Resources and Environmental Management Department (NREM), College of Tropical Agriculture and Human Resources, University of Hawai'i at Manoa.  Since 2002, my research and teaching program of watershed hydrology program have been playing a vital role in NREM where I have been studying natural resources and environmental management in a multi-disciplinary team with complementing expertise in physical, biological, economical, and social sciences. I also have been involved in studying how to solve contemporary natural resource use problems and assisting in sound decision making for optimizing land use and managing agricultural and forestry systems, watersheds, and landscapes in an ecologically sound manner.

Specifically, my research program addresses tropical watershed hydrology using a combination of experimental, theoretical, and numerical modeling across a wide range of temporal and spatial scales.  The ultimate objective of my research program is to promote sound watershed management practices and provide a solid foundation on which to build sustainable watershed and water resources management in Hawaii with conflicting land usages (urban, agriculture, and conservation).

My research program is funded through local, national and international research grants totaling over $ 18.2 million dollars of which over $ 1.3 million dollars for projects that I am serving as the principal investigator.  The modeling component of my research program is supported by different projects among them a project funded by NOAA that aims to evaluate the performance of N-SPECT, a watershed model develop by NOAA, as a management tool to evaluate the effect of land use changes on pollutant movement through coastal watersheds, using field measured data.
