The Journal of Mathematical Physics has recognized Sam Collingbourne as the winner of its 2021 Young Researcher Award. His work on the stability properties of space-times in high dimensions culminated in the winning publication, “The Gregory-Laflamme instability of the Schwarzschild black string exterior.” The judges selected Collingbourne from a pool of JMP authors and the prize includes $3,000. Collingbourne explores solutions to the Einstein equation, which relates the curvature and geometry of space-time to the matter content in space-time.
