PopTech Fellows Justin Gallivan and Nina Dudnik

Justin Gallivan

2010 Science and Public Leadership Fellow Justin Gallivan is amazed by bacteria. You can get them to do almost anything. For instance, Gallivan, associate professor of chemistry at Emory University, told the PopTech crowd Saturday that he can program e. coli bacteria to eat atrazine, a widely used herbicide that can contaminate ground water. The key is to be able to turn the gene on and off. Using a molecule called Riboswitch allows him to do just that. “We want to be able to program the bacteria to send it after atrazine,” he said. “Turns out we can do that.”

2010 Social Innovation Fellow Nina Dudnik told the crowd that her company, Seeding Labs, is taking discarded lab equipment from the United States to needy labs in other countries. “Talent is everywhere,” she said. “We need to train more scientists to be better everywhere.” As part of that commitment, Dudnik said Seeding Labs has also launched a program to connect scientists from the U.S. with their counterparts in Africa and South America. “Just 48 hours ago, the first group of science ambassadors landed in Nairobi,” she said. “Putting scientists from different walks of life together makes everyone’s work better.”
