People

Joe Brown PhD PE (PI) is an environmental engineer with interests in water and sanitation infrastructure, treatment processes, and environmental health microbiology. He is currently Carlton S. Wilder Assistant Professor in the School of Civil and Environmental Engineering, Georgia Institute of Technology. Previously, he served on the faculty of the Department of Disease Control, Faculty of Infectious and Tropical Diseases, London School of Hygiene and Tropical Medicine (LSHTM), University of London. Brown has also been a consultant with UNICEF, the World Health Organization, the World Bank, and numerous other organizations on topics related to water and sanitation. He has an adjunct appointment in the Department of Environmental Health, Rollins School of Public Health, Emory University and is affiliated faculty in the Center for Global Safe WASH. He maintains PE licensure in NC and AL.

Aaron Bivins MSEnvE PE is licensed civil engineer with interests in the relationship between microbial water quality and public health.  He earned his BSCE from Georgia Tech in May of 2007. After five years in engineering consultaning, he returned to Georgia Tech with a narrowed interest in water quality. Following the completion of his MSEnvE, he began his research assistantship with Dr. Brown in the spring of 2014. His PhD Thesis focuses on assessing the human health risks posed by "improved" drinking water sources in low income countries that are subject to operational and maintenance difficulties including intermittent service and hydraulic transients. His goal is to develop a QMRA tool appropriate for use in data scarce contexts which is still capable of incorporating multiple layers of uncertainty to predict human health impacts of microbiologically contaminated water. When not in the lab, reading, or writing, Aaron can be found fly fishing for trout in the rivers and streams of north Georgia.

Jackie Knee MSPH is a public health scientist interested in the field of water, sanitation and hygiene and the interface between environmental microbiology and human health. Following the completion of her BSPH and MSPH degrees at the Gillings School of Global Public Health at the University of North Carolina at Chapel Hill, Jackie was awarded a Fulbright Fellowship and spent a year abroad researching stored rainwater quality in rural Thailand. Upon her return to the U.S., she worked as an environmental scientist in the Waterborne Disease Prevention Branch at the Centers for Disease Control and Prevention before making the decision to return to school and earn her doctorate degree. Jackie is currently in her first semester as a PhD student at Georgia Tech and is researching the relationships between improved sanitation, population density, and child health in peri-urban, informal settlements in Maputo, Mozambique. Outside of work, Jackie can be found running on the Atlanta beltline, eating frozen yogurt, and taking her pup to the dog park.

Trent Sumner MS is a PhD student working on the MapSan study in Mozambique and soil transmitted helminths in the rural American South. Before returning to Tech for a PhD he served as a Peace Corps volunteer in Togo, where he started off teaching and ended up working in rural water and sanitation, where he could put his Tech engineering skill set to best use.
