Stefanie Kroll is the project science director of the Delaware River Watershed Initiative, a collaboration between over 50 nonprofit groups working in watershed conservation. She has a PhD in ecology from SUNY College of Environmental Science and Forestry in Syracuse, NY. She obtained a master’s-equivalent at the University of Castilla-La Mancha in Albacete, Spain, after working in interpretation and translation, and teaching English for several years. Her focus on aquatic ecosystems is not surprising given that she grew up spending summers fishing and canoeing in the lakes and streams of New York State and surrounding areas. She volunteers with the Raritan Headwaters Association and the Tookany-Tacony-Frankford Watershed Partnership. She also works with Academy of Natural Sciences' Women In Natural Sciences program. Previous work includes forest inventory, program support for a nonprofit environmental organization, community assessment of Onondaga Lake and stream surveys throughout Spain.
