Samuel S. Olivier EDUCATION Unversity of California, Berkeley: Berkeley, CA 2017-Present Ph.D., Nuclear Engineering (Expected Spring 2021) Advisor: Rachel Slaybaugh Texas A&M University: College Station, TX 2017 B.S., Nuclear Engineering, Minor in Applied Mathematics; Magna Cum Laude RESEARCH EXPERIENCE Graduate Student Researcher Nuclear Engineering Dept. Fall 2017 { Present University of California, Berkeley High Energy Density Weapons and Complex Integration Summer 2017 Physics Intern Lawrence Livermore National Laboratory Created a generalized nuclear reaction network framework capable of simulating the evolution of an arbitrary number of isotopes for Cosmos++, an LLNL astrophysics code. Created a massively parallel nucleosynthesis post processor to regain isotopic resolution from simulations run with small networks. Used the generalized network and post processor to investigate the e ect of tidal disruption on a white dwarf's composition. Undergraduate Researcher Center for Exascale Radiation Transport Spring 2017 Texas A&M University Implemented the Variable Eddington Factor Method, a nonlinear source iteration scheme, for the 1D neutron transport equation using the Lumped Linear Discontinuous Galerkin discretization for the SN equations and the constant-linear Mixed Finite Element Method for the drift-di usion equation. Showed that the LLDG/MFEM VEF method is as e ective as S2SA, that the method exhibited second order accuracy, and that the thick di usion limit is preserved. In addition, van Leer slope reconstruction was shown to increase accuracy. High Energy Density Weapons and Complex Integration Summer 2016 Physics Intern Lawrence Livermore National Laboratory Implemented a 19 isotope nuclear reaction network into Cosmos++. Veri ed the network with hydrostatic test problems and showed that it is an inexpensive method for modeling stellar evolution. Undergraduate Research Honors and Undergraduate Research Fall 2015 { Spring 2016 Scholars Program Texas A&M University Public presentation and written thesis on designing an electrore ner to purify depleted uranium metal with non-aqueous electrolysis. Lab Technician Fuel Cycle and Materials Laboratory Fall 2014 { Spring 2016 Texas A&M University The Fuel Cycle and Materials Laboratory studies the nuclear fuel cycle, including materials and chemical process- ing, advanced fuels and materials, and waste immobilization. Duties included: research, general lab maintenance, experiment preparation, vacuum pump repair, decontamination and the handling of radioactive materials.
