Postdoctoral Researcher in Physics-Informed Machine Learning for Ice Sheet Model

The Ice Future Lab in the Department of Earth Sciences at Dartmouth College invites applications for a postdoctoral researcher with expertise in ice sheet numerical modeling and machine learning. This is a 2-year full-time position with possibility to extend to three years, preferably starting April 2026, and is funded by the NSF Collaborations in Artificial Intelligence and Geosciences program in collaboration with the Astera Institute. The position is based at Dartmouth College, with primary advising and support provided by the Ice Future Lab.

The project is focusing on developing next-generation, physics-informed AI tools to better understand and predict the contribution of the Greenland and Antarctic ice sheets to sea-level rise. Using the open-source PINNICLE framework, we fuse multi-sensor remote sensing data into a model-ready, "living" data product that provides physically consistent, mesh-free fields of ice geometry, flow, and basal conditions for both ice sheets. We also use physics-informed neural networks and Bayesian uncertainty quantification to learn new, data-constrained parameterizations of basal sliding and iceberg calving at major Greenland outlet glaciers and assess how these processes control future ice loss under different climate scenarios. The work will directly interface with leading ice-sheet models and international intercomparison efforts, producing open datasets, software, and projections that reduce key uncertainties in sea-level rise estimates.

Major Duties/Responsibilities:

• Develop and apply physics-informed neural networks to fuse multi-sensor remote sensing data into a data product for the Greenland and Antarctic.

• Design, implement, and evaluate machine-learned parameterizations of basal sliding and iceberg calving.

• Maintain and extend open-source software PINNICLE, including reproducible workflows, documentation, and example notebooks for the broader glaciology and AI communities.

• Collaborate closely with an interdisciplinary team, contribute to community training activities such as the Glaciology and Machine Learning Summer School.

• Presenting research findings at national and international conferences and publishing results in peer-reviewed journals.

Postdoctoral researchers are advised and hosted in the Department of Earth Sciences. They are also supported by the Guarini School for Graduate and Advanced Studies, including their community initiatives.
