Barry works in the intersection of power and performance. Future supercomputers will be power limited, with an exascale target of only 20 megawatts. His research focuses on both minimizing execution time under a job-level power bound and minimizing turnaround time under a system-wide power bound.

Barry holds a Ph.D. in Computer Science from the University of Arizona, an M.S. in Computer and Network Administration from Florida State University, and a B.A. in Theater from the Honors Tutorial College at Ohio University.
