Ricky Passarelli is a Research Associate with the Environmental Security program at Stimson. His work looks to mitigate global conflicts that arise over shared water resources, environmental degradation, urbanization, and food security. With a background in civil engineering, he is particularly interested in how an improved understanding of environmental systems can influence infrastructure and urban design decisions. His previous research has looked at community-based project design and point-of-use water treatment in rural Africa. Ricky holds both a B.S. in Civil Engineering and a Master’s in Urban and Environmental Planning from the University of Virginia.
