Weber’s research group focuses on the fundamental and applied aspects of radiation effects in materials, the interaction of radiation and charged-particles with solids, ion-beam and electron-beam modification of materials, defect-property relationships in ceramics, long-term performance of materials under extreme environments, phase transformations, interface phenomena, and nanostructures in materials. Their research includes using energetic ion and electron beams to study radiation effects in materials, to structurally modified materials for advanced technologies, and to perform accelerated testing of materials for extreme radiation environments, as well as using advanced computational methods to investigate defect properties, phase transformations, and radiation effects. Weber has authored or co-authored 13 book chapters and over 685 peer-reviewed papers with more than 27,500 times. He has given over 230 invited presentations at national and international scientific conferences, workshops, research institutions, and universities.
