The Post-Doctoral Appointee Program is designed to recruit outstanding Ph.D. applicants to fill specific research needs in a professional cutting-edge technical work environment. Appointments are for one year with possible renewal. Job Summary We seek to hire a postdoctoral researcher who will research and develop probabilistic approaches to enable fault-tolerant and scalable scientific simulations on extreme scale computing platforms. For this work, the postdoctoral fellow will be part of a multi-disciplinary team with expertise in uncertainty quantification, Bayesian methods, numerics, and software development. The role of the postdoctoral fellow will be to develop and implement algorithms for fault-tolerant computing and perform computational investigations to evaluate the effectiveness of the approach on various classes of partial differential equations. The work involves collaboration with other researchers at Sandia and academia. Research programs are expected to result in impactful publications in major scientific journals and widespread recognition within the international scientific research community, as well as relevant contributions to the long-term energy and environmental mission objectives of the U.S. Department of Energy. Required This position requires a PhD in engineering, computational sciences, physical sciences, or mathematics, with a strong interest in one or more of the following research fields: uncertainty quantification, probabilistic methods, and large-scale scientific computing. Security Clearance This position does not currently require a Department of Energy (DOE)-granted security clearance.
