Dona Crawford, Associate Director for Computation at NNSA’s Lawrence Livermore National Laboratory (LLNL), announced her retirement last week after 15 years of leading Livermore’s Computation Directorate. “Dona has successfully led a multidisciplinary 1000-person team that develops and deploys world-class supercomputers, computational science, and information technology expertise that enable the Laboratory’s national security programs,” LLNL Director Bill Goldstein said. “Dona’s leadership in high performance computing has been instrumental in bringing a series of world-class machines to the Laboratory.”
