For his pioneering research in atom probe field-ion microscopy and atom probe tomography, most recently to understand the unprecedented properties and behaviors of nanostructured ferritic steels.
For innovative research in nuclear structure physics, particularly in areas leading to a quantitative understanding of the excitation and decay of the elementary collective modes of nuclei, and for vision and scientific and technical leadership in building the Holifield Radioactive Ion Beam Facility into a forefront laboratory for nuclear science.
