PhD Student
Biography
Raul Palomares holds a B.S. in Physics from the University of Texas at Austin and is currently pursuing his Ph.D. in Nuclear Engineering with a focus on nuclear materials. The goal of his dissertation research is to elucidate the behavior of oxygen defects in oxidized uranium dioxide in order to identify correlations between defect structure, defect stability, and bulk transport properties. This work comprises neutron total scattering experiments performed at the Spallation Neutron Source at ORNL and broadband dielectric spectroscopy experiments performed at UTK. In addition to his main dissertation research, Raul’s work also includes performing structural characterization of lanthanide-doped UO2 systems and swift heavy ion-irradiated oxides (CeO2, ThO2, UO2, GeO2), and performing defect annealing studies on ion-irradiated CeO2 and ThO2.
