Ethan joined the PhD program in the Fall of 2020. His research focuses on modeling radiation hydrodynamics and neutronics. Together with the rest of the team, they have developed a semi-analytic technique for solving the supersonic radiation diffusion equation in curvilinear geometries with an arbitrary boundary condition. They have also developed the variable dynamic mode decomposition, a data-driven modeling process for linear modeling of the extremely large systems that arise when studying multi-physics simulations over varying timescales. VDMD has been published, and we have further developed compressive extensions to VDMD that allow for system size reduction of tens of thousands of times while still generating an acceptably accurate model. VDMD is capable of forming an optimal linear operator while simultaneously performing an eigenvalue/eigenvector decomposition of extremely complicated datasets.
