For his seminal work on elucidating key molecular-scale mechanisms that govern biogeochemical transformation of contaminants, trace metals, and natural organic matter, which has made significant contributions to the understanding of natural organic and metal cycling in terrestrial ecosystems and remediation of contaminated sites, and also for his contributions to the development of the next generation of scientists and engineers.
For pioneering advances in the field of materials chemistry for the design, synthesis and fabrication of new materials and their translation into new energy technologies, including superconductor wires, electrodes for batteries, solar cells, lithium extraction from geothermal brine and additive manufacturing of magnets, and also for his leadership in developing the next generation of scientists and engineers.
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.
For significant contributions and leadership in the processing and properties of materials, particularly intermetallic alloys, which have led to his reputation as one of the world's leading scientists in these areas.
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.
