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 Associate 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.

Drew Capone PhD is a post-doc studying sanitation in low-income settings. After a brief stint in cosmetics manufacturing, Drew taught high school math and chemistry with the US Peace Corps in rural Mozambique. After returning to the US, Drew joined the Brown Water Group to study fecal sludge management in Maputo, Mozambique and worked on the Maputo Sanitation (MapSan) trial to assess the use of environmental matrices for public health surveillance and health impact assessment, receiving his PhD in 2020. Drew is also interested in communities on the margins of US society that experience poor sanitation. He studies open defecation in US cities by people experiencing homelessness and soil-transmitted helminth infections (intestinal worms) among children in rural Alabama.

Kevin Zhu is a PhD student working on novel approaches to fecal source tracking and SARS-CoV-2 monitoring, with funding from the National Science Foundation. He has served as a TA for the core graduate course CEE 6311: Microbial Principles.

Olivia Ginn is a PhD student studying the effects of widespread fecal contamination on air quality and the associated risks. Her studies are based in Kanpur, India and La Paz, Bolivia where there is widespread fecal contamination and potential for transmission of microbes through the air. As a part of her thesis, she works closely with undergraduate students to facilitate application of classroom learning to real world problems. Aside from research, you’ll most likely find Olivia on top of a mountain somewhere in the world or having a banjo/ukulele jam sesh with her three-legged cat but don't worry she also loves dogs.

Former group members

Aaron Bivins MSEnvE PhD PE is an Atlanta native and three-time Georgia Tech graduate. He successfully defended his PhD in October 2019. He is interested in mathematically characterizing the interactions between humans and fecal-oral pathogens particularly interactions mediated by engineered infrastructure. In this PhD work, he used dead-end ultrafiltration and droplet digital PCR to quantify fecal-oral pathogens in drinking water supplies, developing quantitative microbial risk assessment models to estimate human health risks associated with water supplies in underserved settings. Although he is deeply fascinated by microbes, his favorite water quality indicator will always be the trout. He's now heading to Notre Dame as a postdoctoral fellow in Kyle Bibby's group.

Jackie Knee MSPH PhD 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. Jackie researched the relationships between improved sanitation and outcomes of enteric infections and environmental enteric dysfunction in the MapSan trial, set in urban Maputo, Mozambique, completing her PhD in 2019. Jackie has been selected as the 2019 Marshall Sherfield Fellow for post-doctoral training in the United Kingdom - she's now at the London School of Hygiene and Tropical Medicine working in the Environmental Health Group.

David Berendes PhD MSPH (former post-doc, currently at CDC) is an interdisiplinary epidemiologist interested in evidence-based, sustainable, and applied public health solutions to water, sanitation, and hygiene-related diseases. David completed his BS in Molecular Biology from Duke University (Go Blue Devils**) and his MSPH in Global Epidemiology from Emory University. He worked as a research assistant and ORISE fellow in the International Emergency and Refugee Health Branch of the Centers for Disease Control and Prevention in the wake of the Haiti cholera epidemic from 2010 to 2012 before returning to Emory to complete his PhD with Dr. Christine Moe. His dissertation work focused on how coverage of toilets and fecal sludge management in urban neighborhoods is associated with fecal contamination in the public and private (household) domain and enteric infection in children.

Richard Chunga PhD was co-advised with Dr. Jeroen Ensink of LSHTM. Richard is a SHARE-funded student originally from Malawi, where he has worked extensively on sanitation with WaterAID and other organizations.  He has an MSc in Water Management from Cranfield University, an MSc in Project Planning and Management from the University of Bradford, and a BSc in Agriculture and Rural Development from the University of Malawi.  His PhD work focused on ecological sanitation uptake in peri-urban areas of Lilongwe and Blantyre City: "Investigating factors affecting the adoption of ecological sanitation in peri-urban areas: application of the theory planned behaviour". He (successfully) defended his thesis in 2015.

Ameer Shaheed PhD was co-advised with Prof. Sandy Cairncross at LSHTM. Before joining LSHTM, Ameer worked at the World Health Organization.  He received an MSc in Environmental Engineering from Imperial College London and a BSc (Hons) in Biochemistry from the University of Warwick. His field-based PhD research has taken him to Cambodia, Zambia, and Pakistan. He (successfully) defended his thesis in 2015.

Michelo Simuyandi was co-advised with Dr. Val Curtis at LSHTM. Originally trained as a teacher, Michelo comes to LSHTM from the University of Cape Town, where he received a BSc (Hons) in Molecular and Cell Biology and an MSc in Radiation Oncology. He is a researcher with CIDRZ, Zambia, and previously was a member of the Tropical Gastroenterology and Nutrition (TROPGAN) group at the University of Zambia, School of Medicine. He recently led a randomized, controlled trial on a safe water intervention in urban Lusaka, the subject of his PhD work.
