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 fundamental investigations of the structure and dynamics of materials using X-ray diffraction, including pioneering nanosecond resolution X-ray studies and the development of three-dimensional X-ray structural microscopy with submicron resolution.
For the development of advanced X-ray focusing and microfocusing optics and three-dimensional X-ray microscopy, and for pioneering research on the atomic and mesoscale structure of materials.
For his internationally recognized accomplishments in high-energy physics, radiation transport, and detector and neutron target research and development.
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 applying molecular beam techniques to study chemically reactive collisions, helping to lay the foundation for the present field of chemical dynamics, and for pioneering studies in accelerator-based atomic physics, ion-solid interactions, and the channeling of ions, electrons and positrons in crystalline solids.
For discoveries of fundamental importance in mammalian genetics, as well as for studies of genetic and developmental effects in mice, which have provided a broad basis for assessment of the genetic risk to humans from radiation and chemicals, including the development of genetic and early developmental tests now used worldwide.
