Mechanical engineering major Thomas Scott completed an internship with Lawrence Livermore National Lab during the summer 2023 semester.
I am Thomas Scott, an undergraduate senior pursuing a degree in mechanical engineering. During my time at Lawrence Livermore National Lab (LLNL), with the generous support of the Livermore Lab Foundation (LLF), I engaged in a computational engineering project relevant to national defense. This project centered on the validation of models for the novel Direct Laser Impulse (DLI) chamber within the lab’s National Ignition Facility (NIF).
I began by improving the simulated responses of individual cases, identifying relevant physics to prioritize and feasible ranges for the associated parameters. I then developed parallelized parameter exploration and calibration tools, employing Bayesian optimization techniques. Additionally, I created a graphical user interface, facilitating real-time manipulation of input parameters and visualization of study outcomes. The primary objective of these tools was to provide calibration of unspecified parameters and to ascertain uncertainty, incorporating a blend of machine learning algorithms and user-driven inputs, ultimately facilitating efficient while still well-informed conclusions.
In addition to the opportunity to gain real world experience, LLNL and LLF provided many talks regarding lab-related projects, theory, and history. The experience overall was challenging and interesting, while facilitating my early exploration into the field of computational engineering.
