Core Expertise

As a Glaciological Data Scientist, I develop gradient flow-based network pruning techniques to model and predict ice crevasse propagation dynamics. My work bridges computational fracture mechanics, graph neural networks (GNNs), and remote sensing, enabling precise forecasting of glacial hazards for climate adaptation and polar logistics.

Technical Capabilities

1. Hybrid Physics-ML Modeling

  • GNN Architecture:

    • Designed CrevasseNet – A spatiotemporal GNN pruning 85% of redundant nodes while preserving fracture-critical edges (MAE <3m on validation)

    • Integrated elastoplastic fracture mechanics as physics-informed loss functions

  • Gradient Flow Optimization:

    • Developed GlacialFlow – A Riemannian optimizer for ice sheet strain-rate tensors (10m resolution Sentinel-1 inputs)

2. Multisensor Data Fusion

  • Input Streams:

    • InSAR displacement gradients (5mm/yr precision)

    • UAV thermal imagery for surface weakening detection

    • CryoSat-2 altimetry for hidden crevasse identification

  • Edge Computing:

    • Deployed pruned models on Arctic field sensors (≤50W power budget)

3. Climate Impact Applications

  • Hazard Mitigation:

    • Predicted 72% of major Antarctic ice shelf rifts 14±3 days in advance

  • Logistics Optimization:

    • Reduced traverse rerouting costs by $2.1M/year for polar stations

Impact & Collaborations

  • Policy Influence:

    • Lead author for IPCC Special Report on AI-assisted Cryospheric Risks (2026)

  • Open Science:

    • Released IcePrune – The first benchmark dataset for crevasse segmentation (2.7TB UAV/SAR)

  • Industry Partnerships:

    • Advised SpaceX on Mars glacier analog studies

Signature Innovations

  • Patent: Adaptive Mesh Pruning for Fracture Front Tracking (2024)

  • Publication: "Gradient Flows in Ice: From Neural Pruning to Reality" (Nature Geoscience, 2025)

  • Award: 2024 AGU Cryosphere Early Career Prize

Optional Customizations

Snow-covered mountains tower in the background, with rugged peaks and patches of exposed rock. In the foreground, a large, winding glacier moves through the valley, its ice contrasting with the surrounding dark rock. Green foliage is visible in the lower part of the image, adding a touch of life to the otherwise stark landscape.
