What Your Job Will Be Like:

We are seeking a hardworking and dedicated Postdoctoral Appointee to work at the interface between physics- and process based predictive models and large spectral/temporal datasets, specifically focused upon persistently collected streams of multi-sensor electromagnetic data. Forward modeling efforts will include predicting signal source terms, the processes governing them, and their subsequent propagation to deployed sensors. Advanced uncertainty quantification (UQ) and sensitivity analysis (SA) approaches will be used to characterize and calibrate computational models resulting in predictions with quantified uncertainty.

Real-time model calibration, via integrating robust calibration methods within a facility digital twin, will also be pursued.

On any given day, you may be called on to:

Perform self-directed analysis on provided data sets

Present/share results at team meetings with senior staff

Represent Sandia efforts at multi-lab collaboration meetings

Create publications and present results at conferences/workshops
