For leadership and pioneering research in the fundamental effects of radiation on a broad range of metals and ceramics applicable to fission and fusion energy systems.
For distinguished research on the air/surface exchange of atmospheric trace gases and particles and their interactions with the Earth's biogeochemical cycles, and for pioneering developments in atmospheric sampling methodologies with special emphasis on the global mercury cycle.
For distinguished contributions to energy policy research and analysis for transportation, and for advancing understanding of the transportation sector's role in energy and environmental concerns.
For fundamental research establishing fission-imposed limits on rotating nuclei, and for extensive studies of heavy ion reactions from low to ultrarelativistic energies.
For pioneering research in ecosystem theory, ecological modeling, error analysis, hierarchy theory, and landscape ecology and for the development of basic applications in risk assessment and regional environmental analysis.
