Professional Experience

Jamie Bramwell is a simulation software project leader primarily working in the Strategic Deterrence and Engineering directorates. She earned her Ph.D. in Computational Science, Engineering, and Mathematics from the University of Texas at Austin and joined LLNL in 2013 as a computational engineer specializing in advanced finite element methods.

Jamie began her career as an integrated code developer on ALE3D, a large-scale multi-physics simulation code supporting Strategic Deterrence. In this role, she was the primary developer for the implicit solid mechanics physics package, which included modern structural element capabilities to facilitate complex mission analysis efforts at NIF and modernization of numerical solver library infrastructure.

In 2017, she joined the MFEM finite element library team as an engineering application specialist. Her work included developing a new cardiac mechanics simulation tool and creating experimental mini-applications for user tutorials and examples. In 2020, she initiated the Smith project, a modular software development kit based on MFEM designed to enable agile development of sensitivity-enabled, high-fidelity engineering-scale simulations.

Currently, Jamie serves as the Director of the Center for Computational Engineering and the Deputy Associate Program Director for the Weapons Simulation and Computing Computational Physics program.
