For significant impacts to the fields of synthetic biology and biological interfaces, innovations in the use of chemistry and nanotechnology to develop a molecular mechanistic understanding of complex biological systems, and pioneering approaches in chemical imaging through integration with mass spectrometry-based detection.
For his pioneering efforts in silicon carbide–based power electronics, which have paved the way for vehicle and grid infrastructure advancements, enabling transformational achievements in wireless power transfer and electric drivetrain applications, and for the continuing significant impact his accomplishments will have on the global move toward the electrification and decarbonization of the mobility sector.
For his leadership in separations science and technology; for improving nuclear fuel recycling and waste removal; and for leading the development process that was instrumental in the cleanup of waste at the Savannah River Site.
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.
For original studies of the genetic effects of radiation in mammals. A world authority on mammalian mutagenesis, he and co-workers provided the experimental basis for estimating the genetic hazards of radiation to man and for the corresponding recommendations of national and international standards bodies
