Before joining the Humphrey School, Keeler was the program director and lead scientist for the Natural Capital Project — a collaborative partnership between the University of Minnesota, Stanford University, The Nature Conservancy and World Wildlife Fund. Keeler leads a team of experts in ecology, economics, and software development seeking to better communicate and quantify the value of nature. Keeler’s particular expertise is in better understanding the multiple and diverse values of clean water. She also oversees projects on the ecosystem service benefits of urban green infrastructure, the costs and benefits of conservation and restoration, environmental justice implications of parks and green space development, and the sustainable management of agricultural landscapes.
