David earned his doctorate in Environmental Engineering from Duke University, where he examined the fluid mechanics of groundwater remediation and a novel technique to speed up contaminant removal. He was an NSF Graduate Teaching Fellow in K-12 education, which led him to India to teach environmental engineering for two summers. Following graduate school, David was an AAAS Science and Technology Policy Fellow for USAID in the Office of Water. There, he focused on higher education partnerships and water resources management, especially in agricultural projects primarily in Africa. At UVa, David studies the dispersion dynamics of the ceramic water treatment device, Pure Madi, and mentors undergraduate and graduate students in South Africa and Tanzania.
