Robert Foushee

Associate in Research

Robert Foushee performs biological, physical and chemical analyses on liquid and solid sanitation technologies undergoing testing in the lab. He also works with the engineering team on troubleshooting and operating prototypes. Originally from New York City and an avid Knicks fan, Robert moved to Durham ten years ago and joined the hospitality industry. The move south was welcome: between Duke University, RJ Barrett’s Alma matter; the local Foushee Street bearing his last name; and warmer temperatures, Durham feels like home. Robert is the father of four grown children.
