Job Summary

We have an opening for a Physics-Informed Machine Learning Postdoctoral Researcher to develop and apply advanced computational methods for modeling complex physical systems.

You will combine expertise in machine learning computational mechanics and numerical methods to develop physics-informed models that improve the accuracy robustness and computational efficiency of scientific simulations. Research may include developing machine-learning models constrained by physical laws learning constitutive relationships from experimental or simulation data developing surrogate and reduced-order models and integrating data-driven approaches into computational mechanics workflows. This position is in the Atmospheric Earth and Energy Division within the Physical and Life Sciences Directorate.

This position offers a hybrid schedule blending in-person and virtual presence. You will have the flexibility to work from home one or more days per week. 

You will

Develop physics-informed machine-learning methods for computational mechanics and scientific simulation.

Integrate governing equations conservation laws boundary conditions and material constraints into machine-learning models.

Develop train validate and evaluate neural networks surrogate models reduced-order models and other scientific machine-learning methods.

Analyze computational and experimental data to identify physical relationships model parameters and constitutive behavior.

Perform computational mechanics simulations using finite-element finite-volume or related numerical methods.

Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory.

Collaborate with others in a multidisciplinary team environment to accomplish research goals.

Publish research results in peer-reviewed scientific or technical journals and present results at external conferences seminars and/or technical meetings.

Perform other duties as assigned
