Description
This postdoctoral research opportunity at the Naval Research Laboratory (NRL) focuses on computational mechanics and structural-acoustics. The project involves developing physics-based computational approaches to accurately solve wave-dominated problems, particularly the propagation and scattering of acoustic and elastic waves in complex geometries and materials.
Research topics include, but are not limited to:
- New mathematical formulations for scattering from structures with geometric and/or material complexity
- Novel high-order discretization techniques
- Scalable solution methods for indefinite, ill-conditioned linear systems
- Error estimation, mesh generation, and a-posteriori adaptation
- Uncertainty quantification for coupled elasto-acoustics problems
Candidates with the ability to develop and implement algorithms related to these topics are especially encouraged to apply.
Research Environment
The Naval Research Laboratory provides a collaborative environment with access to state-of-the-art facilities and mentorship from leading scientists. The research aligns with NRL’s mission to advance knowledge in computational acoustics and elastodynamics with applications in defense and engineering.
