Why did Remington Poulin decide to make a living in chemistry while still in high school? "It's a whole other language of things you can't see," he tells his hometown newspaper. That heightened sense of scientific curiosity led him from Maryland to Georgia Tech, where he received his Ph.D. last year from the School of Chemistry and Biochemistry under the supervision of Julia Kubanek, a professor of chemistry and biochemistry and of biological sciences. Poulin, now conducting postdoctoral research at the Max Planck Institute for Chemical Ecology in Germany, was the lead author on a new Tech study that for the first time identifies the chemicals in blue crab urine that scare off their prey. Poulin explains how he collected that crab urine and details how the study's findings could lead to better management of crab and oyster farms.
