The next frontier in environmental engineering: Brown tackles public health issues through the microscope

Joe Brown’s research is largely focused on water contamination and its impact on public health. He travels to communities around the world measuring microbes in each environment to gather exposure data and determines what it means for the health and safety of residents. In a recent trip to India, Brown found aerosolized Giardia and Salmonella, pathogens not normally known to be transmitted via air. This discovery creates a new challenge in environmental engineering, one where microbes associated with water and sanitation are transmitted via the air (aerosols), potentially leading to new pathways of disease transmission.

New CDC-sponsored research seeks to understand water-related risks of antibiotic use in agriculture

Joe Brown and a team of Georgia Tech researchers have received a grant from the U.S. Centers for Disease Control and Prevention to study how antibiotic use on poultry farms might impact waterways near and downstream from the farms. They will collect samples in north Georgia to measure antibiotic resistance genes and resistant pathogens in the environment. (Photo: Jess Hunt-Ralston)

A group of Georgia Tech researchers has received $340,000 from the U.S. Centers for Disease Control and Prevention to better understand how poultry feeding operations in Georgia potentially introduce antibiotic-resistant pathogens into the nearby environment.
