Looking to advance the frontiers of research in computational mathematics and scientific computing? Are you passionate about impacting problems of national importance? If so, envision the opportunities as Sandia's next John von Neumann Postdoctoral Fellow.

We are now accepting applications for the 2027 John von Neumann Fellowship in Computational Science. This is one of Sandia's most prestigious postdoctoral fellowships with funding from the Applied Mathematics Research Program in the U.S. Department of Energy's Office of Advanced Scientific Computing Research and Sandia's Lab Directed Research and Development Program. In this position, you will:

Address complex problems in support of mission areas of national importance,

Collaborate with world class researchers on challenging research questions, and

Disseminate your work via leading publication and conference venues.

We are seeking applications from researchers in the broad domain of computational and applied mathematics, including algorithm analysis, applied probability, combinatorial scientific computing, control theory, data science, data driven methods, discrete mathematics, discretization methods, graph algorithms, high-performance computing, integral equations and nonlocal models, inverse problems, linear and multilinear algebra, mathematical analysis, meshing, modeling & simulation, multilevel/multiphysics/multiscale methods, numerical analysis, operations research, optimization, ordinary and partial differential equations, numerical solvers, quantum information science, scientific machine learning, statistical inference, time integration, and uncertainty quantification.

We seek applicants with interest in making a positive impact through the advancement of computational methods for scientific and engineering applications, including additive manufacturing, circuit simulation, computational fluid dynamics (CFD), computational solid mechanics, cyber security, data science, Earth systems, electrical systems, electromagnetics, hyperspectral imaging, machine learning, magneto-hydrodynamics (MHD), micro-electro mechanical systems (MEMS), material design, molecular dynamics, power grid, sensor data fusion, shock physics, signal processing, subsurface flow and mechanics, and turbulence modeling.

The appointment is for one year, with the option of a second year, and includes a highly competitive salary, moving expenses and a generous professional travel allowance. You will pursue a combination of self-directed research and integration with existing Sandia research…
