Keith Taddei

Keith Taddei joined the APS in 2023 as an Instrument Scientist on the 11-ID-D beamline. Previously, he worked as an Instrument Scientist on several neutron diffractometers at ORNL’s High Flux Isotope Reactor. He received his Ph.D. in physics from Northern Illinois University and his B.S. in Physics from Lewis University.  Dr. Taddei’s research focuses on applying the powerful tools of x-ray and neutron scattering to elucidate exotic states of matter in topological and quantum materials. He current work invovles long-range-entangled and symmetry-protected topological states, the physics of low-dimensional systems, and topological superconductivity. As a member of the SRS in the XSD, he broadly applies the principles of x-ray scattering to address big science problems focusing on ways x-ray diffraction can be used to understand orders in materials with technological applications. He is a member of the American Physical Society, American Crystallographic Association, Pittsburgh Diffraction Society, Neutron Scattering Society of America, and the Sigma Xi/Sigma Pi Sigma/Kappa Mu Epsilon honors societies.  He currently serves as the Chair of the American Crystallographic Association’s Neutron Scientific Interest Group and is active in the GMAG section of the American Physical Society. He serves as a referee for the Physical Review Journals as well as for several Nature and Elsevier journals. Dr. Taddei has served as an organizer of the annual Neutron and X-ray Scattering school co-hosted by ORNL and ANL and a lecturer at the annual Magnetic Structure Solution Workshop.
