  Graduate Research Assistant (Aug 2004 – Present)
  San Diego State University, Physics Department
  Advisor: Calvin W. Johnson
  Funding from the Department of Energy through LLNL. Improve the a nuclear shell model program (REDSTICK) for a high performance computing environment, and use the program to perform frontier calculations investigating nuclear structure. REDSTICK, a nuclear shell model program written in Fortran 90 and MPI, involves solving a matrix eigenvalue problem for a large (dimensions > 108), sparse unstructured matrix, using the iterative Lanczos method. The output is the energy spectrum and wavefunctions, to be used in additional nuclear structure calculations.

  Thesis Research: Investigate the effects on nuclear properties of 3-body forces on high p-shell and low sd-shell nuclei. In order to complete these calculations, significant improvements are needed within REDSTICK to optimize its run-time performance and overcome severe memory limitations.

  Summer 2007 - Summer Student. Mentor: W. Erich Ormand
  Lawrence Livermore National Laboratory, N-Division
  Upgrade REDSTICK capabilities from a 2-body nuclear shell model code to a 3-body code. Create 6 new subroutines and integrate them into the existing code (this requires modifying half of the 65+ subroutines in REDSTICK).
  
  Summer 2006 - Summer Student. Mentor: W. Erich Ormand
  Lawrence Livermore National Laboratory, N-Division
  Create a subroutine implementing a new search algorithm for one-body jumps in REDSTICK to optimize its serial run-time performance. Subroutine run-time speed improved from 4 to 8 times faster than the existing algorithm.

• Modeling the Foucault Method of Lorentz Microscopy on Monodomain Nanoparticles to Determine Magnetization
  Graduate Research Assistant (Aug 1998 – May 1999)
  Carnegie Mellon University, Pittsburgh, PA
  Advisor: Sara Majetich
  Created a program in IDL to model and visualize the Foucault method of Lorentz microscopy on a monodomain spherical nanoparticle, including the effects of Lorentz deflection of the electrons by the particle fringe field, Aharanov-Bohm phase shift induced in the wavefunction passing through different regions, and aperture shift blocking the contributions from specific electrons. This model was used to prove the validity of the Foucault method of Lorentz microscopy as a method of determining the magnetization direction of a monodomain nanoparticle, with potential use commercially as a memory storage technology.
