Research key words: climate change, hydrology, runoff, water resources, urban growth, land use change

My research is centered around the intersection of climate change, hydrology, and urban growth. Over the several years, I have been interested in climate change and urban growth impacts on the hydrology and water quality at basin scales, evaluating hydroclimatic data sets for hydrological analysis and modeling, and effects of urban-rural climatic difference on hydrology. More recently I began to explore new data sources for hydroclimatic research (via Milwaukee Urban Observatory) and study the trends and propagation of drought.
