Position Summary
The Cryosphere & Climate Lab within the Department of Geography at Penn State University seeks a Postdoctoral Researcher (or Researchers) to conduct cryospheric research under two funded projects:
1. NASAFunded Antarctic Supraglacial Hydrological Observations
This project is advancing the observational understanding of Antarctic supraglacial hydrology by integrating optical and radar satellite imagery ICESat-2 laser altimetry and machinelearning techniques to map and quantify lake depths and volume across the Antarctic ice sheet. The postdoc will retrieve lake depths from ICESat2 train machinelearning models to estimate depths from optical imagery and scale up lake volume mapping across Antarctica. Resulting lake dynamics insights will inform improved climatemodel parameterizations and ice shelf vulnerability assessments.
2. ISMIP7/HeisingSimons Foundation IceShelf Collapse Projections (24 months)
Within the Ice Sheet Model Intercomparison Project for CMIP7 (ISMIP7) framework the postdoc will help finalize and advance protocols for implementing Antarctic ice sheet calving and hydrofracture processes in icesheet models. Responsibilities include running a machinelearning firn densification model emulator using reanalysis and climate model outputs generating firnair content and meltwater datasets assessing climatemodel biases and evaluating thresholds for supraglacial lake formation and iceshelf instability.
Key Responsibilities
Lead development and application of remote sensing and other machine learning workflows for supraglacial water mapping and depth retrieval.
Implement established protocols to estimate supraglacial lake depths from satellite mutispectral and ICESat2 data.
Configure and run a firn densification model emulator using climate model outputs.
Generate datasets necessary to implement ISMIP7 ice shelf collapse protocol.
Perform sensitivity analyses evaluate model outputs and estimate hydrofracture potential.
Write manuscripts present at conferences and mentor students in data-driven cryosphere research.
Minimum Qualifications
Ph.D. in Glaciology Geophysics Geography Earth System Science or related field by start date.
Expertise in remote sensing (Landsat Sentinel-1 Sentinel-2 ICESat2) and open-source machine learning toolkits (scikit-learn TensorFlow PyTorch).
Experience with reanalysis datasets and ice sheet and/or climate models.
Proficiency in Python Jupyter Notebooks and high-performance computing.
Publication record and excellent communication skills.
Preferred Qualifications
Research experience related to ice sheet surface mass balance and hydrology.
Familiarity with ice sheet models and intercomparison projects (e.g. ISMIP6 ISMIP7).
Experience with collaborative multiinstitution research.
Funding and Appointment Details
We are ideally seeking one postdoctoral researcher to contribute to both projects.
The position will start as soon as possible.
Salary and benefits follow Pennsylvania State University guidelines.
Travel support is included.
Location: Department of Geography Pennsylvania State University University Park PA.
Application Materials
Submit a single PDF containing:
1. One-page cover letter outlining research interests and qualifications.
2. Current curriculum vitae.
3. Names and contact information of three references.
4. One representative publication (or presentation) in PDF format.
Application Deadline: September 24 2025
