Research Interests

Woonsup Choi’s research activities emphasize understanding of the effects of climate change and urbanization on water-related environmental problems. In this context, he has conducted research on the potential impacts of climate change and land use change on the hydrology and water quality for several regions in the United States and Canada. The approach is mostly combining simulation models with various climatic and land use change scenarios. Currently, his work focuses on the effect of urban areas on future climate scenarios and how it is going to affect the results from hydrological simulations. As preliminary work, he analyzed the spatial and temporal patterns of urban climate in the Midwest with financial support from the UWM Graduate School Research Committee. He also embarked on research fieldwork in Seoul, Korea to examine water quality in small streams that recently underwent restoration projects.
