About this position

The Mathematics in Computation Section at Oak Ridge National Laboratory invites applications for the Alston S. Householder Fellowship in mathematics and scientific computing, a postdoctoral fellowship supported by the Applied Mathematics Research Program in the U.S. Department of Energy’s Office of Advanced Scientific Computing Research.

The fellowship is designed for outstanding early-career researchers in computational and applied mathematics who want to combine self-directed research with integration into existing ORNL projects. The selected fellow will work with a senior staff mentor and collaborate with researchers across ORNL on mathematically grounded problems connected to scientific and national priorities.

The advertised research scope is broad and spans algorithm analysis, artificial intelligence, combinatorial scientific computing, control theory, data science, data-driven methods, discrete mathematics, graph algorithms, high-performance computing, integral equations and nonlocal models, linear and multilinear algebra, machine learning, mathematical analysis, mathematics of data, modeling and simulation, multiscale methods, numerical analysis, optimization, ordinary and partial differential equations, numerical solvers, quantum information science, statistics and probability, and uncertainty quantification. ORNL emphasizes mathematical methods and algorithms that support modeling complex physical, chemical, engineered, and biological systems, alongside computational science activities in extreme-scale computing and data analysis, storage, and visualization.

This fellowship honors Dr. Alston S. Householder and his contributions to numerical analysis and scientific computing. The appointment is intended for researchers who can produce high-impact work, contribute to ORNL’s mathematics and computer science mission, and grow into scientific leadership within a highly collaborative national laboratory environment.

The role offers a chance to engage with world-class researchers in an active laboratory setting and to contribute to the laboratory’s principal areas of research in mathematics and computer science.

Funding details

Two-year postdoctoral appointment with a highly competitive salary, moving expenses, and a generous professional travel allowance; extensions subject to performance and funding availability.

What's required

Applicants must have a Ph.D. in applied or computational mathematics or a related area such as computer science, physics, engineering, or statistics, conferred after January 1, 2023 and no later than August 2027. The research proposal must be mathematical in nature and relevant to computational, scientific, engineering, or analysis work at ORNL. Applicants should have strong collaborative and interdisciplinary ability, excellent written and verbal communication and interpersonal skills, community leadership experience, related professional experience, software development experience in languages such as C++, C, Fortran, MATLAB, R, Python, or Julia, and experience with high-performance scientific computing.
