Stephanie Brink is a computer scientist in the Center for Applied Scientific Computing at Lawrence Livermore National Laboratory. Her research focuses on power-constrained high performance computing and parallel performance analysis tools.

Stephanie received M.S. and Ph.D. degrees in Computer Science from the University of Oregon in 2016 and 2019, and a B.S. degree in Computer Engineering from the University of the Pacific in 2013. At UO, Stephanie was a member of the CDUX Group led by Hank Childs. Her dissertation work focused on power/performance tradeoffs for scientific visualization workloads on supercomputers.
