Daniel White is a research engineer in the Computational Engineering Division at LLNL. Dr. White worked in computational electromagnetics for many years, developing the EMSolve suite of computational electromagnetics codes. EMSolve included finite difference, finite element, and integral equation methods, in both the time domain and frequency domain. Dr. White then transitioned to magnetohydrodynamics and pulse power problems. Then he transitioned to topology optimization for additive manufacturing applications. Currently, Dr. White is applying machine learning methods to diverse engineering problems such as shape optimization, accelerating the simulation of structural lattices, and studying the onset of instabilities in fluids.
Outside of LLNL, Dr. White taught in the Mathematics and Computer Science Department at Cal State East Bay. Dr. White served as an Associate Editor of the SIAM Journal on Scientific Computing for four years. Before joining LLNL, Dr. White was a Senior Engineer at Hughes Electronics , where he was involved in radar signal processing, electromagnetic scattering, and antenna design.
