Portrait of Dr. Stephen Taller

Stephen A Taller

Alvin M. Weinberg Fellow, R&D Associate

Dr. Stephen Taller joined ORNL in 2020 as an Alvin M. Weinberg Fellow in the Nuclear Energy and Fuel Cycle Division. Prior to joining ORNL, he was a postdoctoral fellow at the University of Michigan and completed a Ph.D. in Nuclear Engineering and Radiological Sciences at the University of Michigan in 2020. Stephen Taller has extensive experience in designing, conducting, and analyzing experiments to study radiation damage effects in neutron irradiated and ion irradiated materials, primarily using transmission electron microscopy. Stephen currently serves as a member of several professional and technical committees and as co-chair of ORNL's PRISM employee resource group
