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.

Waste reuse strategies could take a big bite out of greenhouse gas emissions in China’s cities

Air pollution hangs over a portion of Beijing, China. A new study by researchers from Georgia Tech, the University of Minnesota, Yale University and partners in China finds that cities could cut greenhouse gas emissions by a third, significantly improving air quality and health, by adopting a series of strategies to reuse industrial waste.

Cities in China could cut greenhouse gas emissions by more than a third if they were to adopt a series of strategies that reuse industrial byproducts for things like heating or construction material.

Smart Cities: Innovative approaches combining engineering, technology and the social sciences are boosting the urban IQ

Smart Cities graphic with a rendering of the city of Atlanta.

Georgia Tech has been intensifying its smart cities initiative, including membership in the national MetroLab Network and the launch of a new faculty council with members from more than a dozen university units. Tech has long been working in the, but the now the Institute is organizing all the research that’s happening to have a bigger impact.

Journal names Ivey’s paper on sourcing and counting pollution from atmospheric reactions the best of 2016

A paper that grew from Cesunica Ivey's doctoral research in the School of Civil and Environmental Engineering has been named one of the two best papers in Frontiers of Environmental Science & Engineering for 2016. The article outlines a new way to estimate the amount and source of secondary PM2.5 pollution in the air.

Cesunica Ivey’s paper outlining a new way to estimate the amount and source of air pollution has been named one of the two best articles published in 2016 in the journal Frontiers of Environmental Science & Engineering.

Water, water everywhere: In the world of water research, underserved communities provide the ultimate learning ground for undergrads

Water, water everywhere: In the world of water research, underserved communities provide the ultimate learning ground for undergrads.

As if singlehandedly leading a dozen undergraduates at a time in the realm of real-world research isn’t enough of a challenge, Joe Brown ups the ante, carrying his undergrads to conduct fieldwork overseas — in a foreign-language country.

Georgia Tech’s scientific and engineering honor society has recognized Despina Tsementzi’s doctoral dissertation as one of the best of the year. Tsementzi, who finished her Ph.D. in the fall, has won the Sigma Xi Best Ph.D. Dissertation award for 2017. She’s one of only 10 students across campus to earn the distinction.

Study sheds light on key role for ‘rare’ aquatic microbes in dealing with pollution, balancing ecosystems

School of Civil and Environmental Engineering researchers have found that bacteria present in only small numbers in freshwater systems contain key genes that help the broader microbial community respond to environmental changes such as pollution or oil spills. The team used water from Lake Lanier northeast of Atlanta to test how microbial communities respond to common organic compounds. (Photo Courtesy: PBT1981 via Wikimedia Commons)

Even bacteria found in small numbers in freshwater communities play an essential role in maintaining the ecosystem and responding to environmental changes, according to new work from researchers in the School of Civil and Environmental Engineering. This “rare biosphere,” as they called it, carries important genes for breaking down organic pollutants, which can help the entire microbial community withstand environmental changes. Their study appeared March 3 in the journal Applied and Environmental Microbiology.

Danger in the air? Brown wins NSF CAREER grant to find out

Assistant Professor Joe Brown has won an Early Career Development Award from the National Science Foundation. These so-called CAREER grants recognize promising young faculty with funds to help them establish the research director of their careers. (Photo: Jess Hunt-Ralston)

When Joe Brown went to India last summer, he was hoping to collect samples that could help answer some questions he’d been thinking about for a while. His years studying sanitation and global health had given him the idea that the open sewers and overflowing latrines common in the dense cities of the developing world could be linked with disease through an unusual mechanism: airborne transmission of pathogens.

Tech Environmental Engineering Professor Armistead “Ted” Russell has traveled the world, including China, India and Minneapolis, studying air quality and its impacts on urban life. He is also part of a team of scientists, policymakers and industrialists working with a U.S. National Science Foundation Sustainability Research Network to build better cities.
