Daniel White is the Deputy Division Leader of the Computational Engineering Division at LLNL. In this role Dr. White supervises approximately 60 engineers and scientists who work in the areas of electromagnetics, mechanics, defense systems, energy, materials, structures, and fluids. Dr. White attempts to stay technically involved in several projects. Currently, he is Principle Investigator on a DARPA project, he is Principle Investigator on an LDRD on the topic of model order reduction, and he consults on several projects that involve electromagnetic signatures and interactions.

Dr. White earned his Ph.D. in Computational Science from the College of Engineering at the University of California, Davis. He completed his B.S. and M.S. degrees in Electrical and Computer Engineering, also from UC Davis in 1985 and 1986, respectively. He is a member of the Institute of Electrical and Electronics Engineers, the American Physical Society, and the Phi Kappa Phi and Tau Beta Pi academic honor societies. He is currently serving as an Associate Editor of the SIAM Journal on Scientific Computing. 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.
