Purpose:
The Computer Science and Mathematics Division is seeking an applied mathematician and computational scientist to aide in the development of scalable algorithms for uncertainty quantification (UQ). Important to this position is also the design and implementation of such methods on large-scale platforms with application advanced fluid dynamics, transport, turbulence and combustion.
Major Duties/Responsibilities:
The position requires collaboration within a multi-disciplinary research environment consisting of mathematicians, computational scientists, computer scientists, experimentalists, and engineers/physicists conducting basic and applied research in support of the Laboratorys missions. Specific responsibilities include participating in the development and design of multi-scale, multi-physics algorithms, design and implementation of scalable numerical methods for UQ, collaboration with experts from various scientific disciplines on UQ and applications, and following team planning, goals and quality processes.Application areas of particular interest include computational fluid dynamics (including low-speed, incompressible, free-surface flows, multi-phase and multi-component flows, and high-speed, low-density flows), design and analysis of nuclear fuels and reactor simulations, advanced electrochemical storage systems (batteries).
Qualifications Required:
The minimum required education is a Ph.D. in applied mathematics or computational science. Strong background in numerical and functional analysis, probability theory and partial differential equations. Expertise in more than one area of particular relevance to simulations of interest, such as: Nonlinear and linear discretization techniques for coupled multi-physics problems under uncertainty (stochastic finite elements, stochastic finite volume, stochastic finite differences, stochastic least squares), Multi-scale methods, Nonlinear filtering, large-eddy simulations, advanced closure approximations Adaptive high-dimensional approximation. Demonstrated experience in the design and implementation of numerical algorithms in one or more high-level computing languages within a team environment Effective interpersonal skills. Demonstrated written and oral communication skills.Desired Skills Experience working in a multi-disciplinary research environment. Experience in the development of large-scale numerical algorithms and simulation codes. Experience with C++, generic programming, object-oriented analysis, and scripting languages. Software design education or experience.Additional InformationApplicants cannot have received the most recent degree more than five years prior to the date of application and must complete all degree requirements before starting their appointment. Certain exceptions may be considered.This position is a temporary, full-time assignment for 24 months.Technical QuestionsContact Clayton Webster ( THIS EMAIL ).
