ABERDEEN PROVING GROUND, Md. — U.S. Army scientists analyze unknown samples to determine whether hazardous chemical or biological warfare agents are present. Samples come from around the world.
Jennifer Exelby, a chemist, leads 10 chemical-agent handlers for the U.S. Army Research, Development and Engineering Command’s Edgewood Chemical Biological Center, or ECBC.
“I never would have thought that I would be working with chemical warfare materials,” said Exelby, who serves as the acting chief of the Chemical Operations Branch. “This is a world that I didn’t even know existed until I got the job at ECBC.”
