Keith Taddei came to ORNL in 2016 with the purpose of applying the powerful tools of neutron scattering to elucidate exotic states of matter in magnetic and quantum materials. He is currently an Instrument Scientist on the POWDER and WAND2 neutron diffractometers where he develops the capabilities of neutron diffraction and drives research projects in long-range-entangled and symmetry-protected topological states, the physics of low-dimensional systems, functional magnetic materials, and topological superconductivity. As a member of the Powder Diffraction Group of the Neutron Scattering Division in the Neutron Sciences Directorate, he broadly applies the principles of neutron scattering to address big science problems focusing on ways neutrons can be used to understand magnetism in materials with technological applications.
Previously Dr. Taddei was a member of the Neutron and X-ray Scattering Group at Argonne National Laboratory where he studied intertwined orders in low dimensional superconductors to help uncover the mechanism behind unconventional superconductivity. Dr. Taddei 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 in helping organize the Annual March Meeting. He serves as a referee for the Physical Review Journals as well as for several Nature and Elsevier journals. Dr. Taddei is 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.
Dr. Taddei received his Ph.D. in physics from Northern Illinois University with a joint position as a graduate researcher at Argonne National Laboratory. For his dissertation work he was awarded a Dissertation Completion Fellowship, recognized as a 2016 Outstanding Graduate Student in Physics, and awarded the 2015 Margaret Etter Award by the American Crystallographic Association. He received his B.S. in Physics from Lewis University.
