Congratulations to Dr. Walter J. Williams on successfully completing his PhD! Dr. Williams was advised by Professor Okuniewski, and his research focused on the crystallographic evolution within the uranium-zirconium system via time-of-flight neutron diffraction, SEM, and TEM following a novel fabrication method. Their work quantified the thermal response of the material including thermal expansion, phase morphology evolution, isotopic thermal motion of atoms, and proposing a new U-Zr phase diagram. After graduation, Dr. Williams will be joining Idaho National Laboratory.
