Biography

Professor Emeritus Elmer Lewis is a leading authority in Mechanical Engineering, particularly in the areas of computational methods in neutron transport and nuclear reactor physics. His research specializes in integrating finite element methods for solving the Boltzmann equation in neutron transport problems across a six-dimensional space-angle-energy phase space. Significant applications of his work focus on the simulation of neutron transport within nuclear reactor cores, contributing to safety and efficiency advancements. Current research interests include developing hybrid finite element and finite subelement formulations to adequately manage spatial variables, as well as leveraging tailored spherical harmonic expansions to enhance solution methodologies with preconditioned Krylov algorithms for parallel computing environments. In addition to his technical contributions, Lewis's work includes examining reliability risk assessment within engineering design processes, specifically how technical experts and the public perceive risks associated with modern technologies. His extensive publication record includes notable articles in nuclear science and engineering, reflecting his impact on the discipline and advancing knowledge in reactor physics.
