Lawrence Livermore physicists Andrea (Annie) Kritcher and Ronnie Shepherd have been named 2022 fellows of the American Physical Society, Division of Plasma Physics. Kritcher was selected for leadership in integrated hohlraum design physics leading to the creation of the first laboratory burning and igniting fusion plasma. Shepherd was named for contributions to high-energy-density plasma research through short-pulse laser experiments, for time-resolved diagnostics for these experiments, and for sustained mentoring of numerous early-career scientists.

The Intergovernmental Panel on Climate Change (IPCC), a joint awardee of the 2022 Gulbenkian Prize for Humanity, was cited for producing scientific knowledge, alerting society, and informing decision makers of climate change and loss of biodiversity. Lawrence Livermore climate scientists have contributed to each of the IPCC’s assessment reports. The Laboratory’s Program for Climate Model Diagnosis and Intercomparison; the Earth System Grid Federation consortium, initiated by Livermore computer scientists; and the Department of Energy’s Exascale Earth System Model, led by Lawrence Livermore; provide key climate model data and insights to the IPCC.

The American Physical Society awarded its inaugural Neil Ashcroft Early Career Award for Studies of Matter at Extreme High-Pressure Conditions to Lawrence Livermore research scientist Richard Kraus for his achievements and leadership in extreme high-pressure science, including novel measurements of material properties, creation of complete equations of state, and ensuring the future of the programmatic science. Kraus’s study of materials performance under extreme conditions has applications in stockpile stewardship, threat reduction, and planetary sciences.

Bruce Remington received the 2023 American Physical Society (APS) George E. Duvall Shock Compression Science Award, which recognizes contributions to understanding condensed matter and nonlinear physics through shock compression. Remington was honored for pioneering use of high-energy lasers to study Rayleigh-Taylor-driven plastic flows at high pressures, strains, and strain rates. Remington is an APS fellow and a recipient of the John Dawson Award for Excellence in Plasma Physics Research and the Edward Teller Medal.
