Job Description

The Artificial Learning and Intelligent Systemsgroup in NLR's Computational Science Center has an immediate opening for a Postdoctoral Researcher to pursue a cross-disciplinary research project in cross-scale learning from heterogeneous evidence (lab-scale to pilot-scale) relevant to the DOE Office of Critical Minerals and Energy Innovation..

The successful applicant will develop methods that combine evidence across different experimental scales, conditions, and modalities to make predictions at unseen physical or operational scales where data may be sparse or unavailable. In this context, the relationships between inputs and outputs may change with scale, and the available data may come from different data sources with different modalities and amounts and have different physical contexts. We are looking for someone who has developed innovative learning methods, including multi-modal and surrogate modeling approaches, transfer learning techniques, physics-informed ML, and/or statistical learning methods.

Basic Qualifications
Must be a recent PhD graduate within the last three years.

* Must meet educational requirements prior to employment start date.

Additional Required Qualifications

• Demonstrated experience developing ML models for scientific or engineering systems
• Demonstrated experience in learning from one set of conditions or domains and predicting in another, including situations where the source and target distributions differ.
• Demonstrated experience in combining data with different modalities, sampling rates, resolutions, fidelities, measurement characteristics, costs, accuracies, or experimental conditions.
• Demonstrated experience in physics-informed and hybrid modeling, showing the ability to incorporate mechanistic models, physical constraints, or known relationships when useful, without assuming that complete physics models are available.
• Demonstrated experience in model representation and adaptation, how to represent changes in system context, operating conditions, geometry, or scale so that the model can distinguish what is transferable from what is not.
• Excellent communication skills
• Demonstrated experience working in multi-disciplinary teams and collaborative software development
• Demonstrated experience with python and version control

Preferred Qualifications

Job Application Submission Window

The anticipated closing window for application submission is up to 30 days and may be extended as needed.
