At the time, he accepted the news with an attitude as down to earth as his trademark wardrobe of Converse sneakers, shorts and a T-shirt.
"The value of winning the MacArthur, the attention it brings, gives me a chance to tell young people out there who are being discouraged and told 'no' to not believe it — to hang on to their dreams," Roth said.
Roth's own dreams — and dogged determination — led him to captain his high-school track and cross-country teams three years in a row, despite getting cut from the track team after his freshman season. His success in high-school track led to running track and cross country at the University of Oregon.
Despite average grades, Roth's intensity as a runner matched his tenacity as a student. Eventually he earned a bachelor's degree in biology from Oregon and a doctorate in molecular biology from the University of Colorado. Then he spent four years in postdoctoral research at the Carnegie Institution of Washington in Baltimore.
Since joining the Center in 1989, Roth has explored a variety of research paths, but his development of "hibernation on demand" has garnered the broadest attention.
Using minute amounts of hydrogen sulfide to temporarily dim metabolism and thereby reduce the need for oxygen, Roth has successfully induced a state of reversible metabolic hibernation in mice and other model organisms. One day the technique may be used to buy time for critically ill trauma patients on organ-transplant lists and in operating rooms, emergency rooms and battlefields.
His findings have appeared in an array of scientific journals and grabbed headlines around the world. But perhaps the greatest evidence that Roth has hit his scientific stride is the increasing frequency with which references to his work turn up in pop culture, including an entry in "Ripley's Believe it or Not! Special Edition 2007" entitled, aptly, "Mice on Ice."
"You know you've really made it when you're featured in 'Ripley's,'" he said with a grin.
