Kristen Welsh is an isotope hydrologist focused on global water resource management. She uses interdisciplinary approaches in her research and teaching to examine the challenges of managing freshwater resources as climate change and social pressures result in dramatic changes to local hydrology.

Welsh is especially interested in the effects of climate change and extreme weather on freshwater resources in vulnerable coastal communities. Her primary regions of study are the US, Latin America, and the Caribbean, and her current research is investigating the impacts of hurricanes on island freshwater sources.
