Eric O’Quinn

Research Assistant Professor

Biography

CV (Curriculum Vitae)

Eric C. O'Quinn is a research professor in the DISMAT group, specializing in the characterization of heterogeneous disorder in complex oxides and far-from equilibrium processing of materials under extreme conditions. He received his PhD in Nuclear Engineering from the University of Tennessee in 2019, where he also completed his postdoctoral research and currently holds a faculty position. Prior to that, he was a Graduate Research Fellow at Oak Ridge National Laboratory. Eric's research focuses on understanding the behavior of materials under extreme conditions, including high temperatures, radiation, and mechanical stress. He has published articles in high-impact journals on topics such as radiation-induced disorder in complex oxides and the use of advanced characterization techniques to understand material behavior.

Research

O’Quinn’s research interests cover the structure, energetics, and properties of disordered materials, with a particular emphasis on materials under extreme conditions, such as those relevant to the nuclear fuel cycle. Projects include study of the fundamental physics of radiation-matter interactions, stability of energy materials under highly ionizing radiation, and the use of neutron scattering approaches to investigate materials far-from-equilibrium (see his recent talk on this subject here).
