For distinguished research in the field of risk assessment, including pharmacokinetic and pharmacodynamic models, interspecies extrapolation, and human exposure to dioxin and other background contaminants, and for significant contributions to environmental policy through pioneering investigations of the effectiveness of remediation technologies and through service on national and international advisory panels and boards
For fundamental studies of the microscopic structure of magnetic materials using neutron scattering methods, and for contributing to the development of neutron polarization analysis as a productive scientific technique.
For contributions to understanding plasma turbulence and the nonlinear properties of magnetohydrodynamic instabilities, especially their role in explaining the behavior of magnetically confined plasmas, and for development of new magnetic confinement concepts that overcome these limitations.
