Overview:

The Computational and Applied Mathematics Group at Oak Ridge National Laboratory invites applicants for a post-doctoral research position for development of novel algorithms for extreme scale computing with applications to uncertainty quantification (UQ) for simulations of additive manufacturing. Algorithms will be implemented in the Tasmanian UQ library and multiple physics simulation codes will be used including Truchas, MEUMAPPS, and Tusas.

In particular, the application of novel algorithms to scientific discovery will require an entirely new focus on algorithmic development and mathematical rigor than what has been produced by the commercial sector. The application of novel algorithms to problems of interest to the DOE, or for scientific discovery, must leverage the large body of high-performance algorithmic development with mathematics driving advances in the following major thrusts of research:

(1) formulate novel mathematical tasks which are achievable given the type (plentiful or sparse) and form (labeled or unlabeled, static or online, deterministic or noisy) of observational data; (2) design of architectures/models which accurately capture the complexities of the data, with robust estimates of confidence in predictions on defined domains; (3) fast and scalable algorithms to fit the proposed models to data, with a theory that explains the convergence and success of these techniques; and (4) detailed re-analysis of the performance of the trained models to determine underlying processes that govern the given data.

This particular position focuses on the potential for the use and development of tools from the mathematical sciences, as opposed to traditional statistical theory or engineering tools, to support and advance the understanding of extreme scale computing technology, and to accelerate algorithmic performance on leadership computing platforms.

Major Duties and 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 Laboratory’s missions. Specific responsibilities include:

Participating in the development of innovative theoretical analysis and computational methodologies for deep and/or machine learning technologies, customized to large-scale scientific applications, including: additive manufacturing; quantum material design; scientific imaging for material discovery; medical and tomographic imaging; population and evolutionary dynamics; cyber security and power grid analysis; consumer behavior and market analysis; as well as uncertainty quantification for engineered systems. Collaboration with experts from various scientific disciplines and applications, and following team planning, goals and quality processes. Authoring peer reviewed papers, technical papers, and reports. Maintaining memberships in professional, academic, and research organizations.

Basic Qualifications:

Applicants are required to have a Ph.D. either in mathematics, computer or computational science, or a closely related field. Previous experience in C++ 2011 is required.

Preferred Qualifications:

Familiarity of Python and Fortran is desired 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. Technical Questions Contact Miroslav Stoyanov (stoyanovmk@ornl.gov)

Additional Information:

Applicants cannot have received their Ph.D. more than five years prior to the date of application and must complete all degree requirements before starting their appointment. The appointment length will be up to 24 months with the potential for extension. Initial appointments and extensions are subject to performance and availability of funding.
