Summary
Professor Powers received an S.B. in Physics and an S.B. in mathematics from the Massachusetts Insitute of Technology in 1989. In 1995, he received his Ph.D. in Physics from the University of Pennsylvania, with Prof. Phil Nelson serving as his advisor. After Penn, he held postdoctoral positions in the physics departments of Princeton University and the University of Arizona with Prof. Ray Goldstein. Then he was a postdoctoral fellow at Harvard University with Howard Stone in the Division of Engineering and Applied Sciences. He joined the Division of Engineering of Brown University in 2000 as the first holder of the James R. Rice Term Chair in Solid Mechanics. He is currently an associate editor of Reviews of Modern Physics.
