Core Expertise

As a Paleomagnetic Data Scientist, I develop advanced machine learning models to predict geomagnetic field variations over millennial timescales by analyzing sedimentary and volcanic records. My work bridges computational geophysics, Bayesian statistics, and geodynamo theory, enabling high-resolution reconstructions of Earth's magnetic field behavior for both academic and industrial applications.

Technical Capabilities

1. High-Resolution PSV Modeling

  • Data Fusion Framework:

    • Integrated sedimentary records (δ¹⁸O stratigraphy) with lavas (Ar/Ar dating) to resolve directional changes at 100-year resolution

    • Developed MagNet-LSTM, a hybrid model reducing prediction errors by 40% vs. traditional spherical harmonic approaches

  • Uncertainty Quantification:

    • Implemented Monte Carlo dropout in neural networks to estimate confidence intervals for declination/inclination predictions

2. Geodynamo-Informed AI

  • Physics-Constrained Learning:

    • Embedded core-mantle boundary (CMB) heat flux constraints into gradient descent optimization

    • Discovered 1,450-year cyclicity in virtual axial dipole moments (VADM) through wavelet analysis of Holocene data

  • Paleosecular Atlas:

    • Built the first global interactive database of PSV predictions (0–100 ka BP), cited in 120+ studies

3. Applied Paleomagnetism

  • Tectonic Applications:

    • Resolved plate rotation controversies in the Mediterranean using PSV-assisted plate reconstructions

  • Industrial Uses:

    • Improved hydrocarbon reservoir dating accuracy by 25% for major oil companies

Impact & Collaborations

  • Mega-Project Leadership:

    • PI for PALEOMAG-10K – An international effort to standardize PSV chronologies

  • Policy Influence:

    • Advised UNESCO on magnetic anomaly impacts for World Heritage site dating

  • Open Science:

    • Released PaleoMagML – The first transfer learning toolkit for regional PSV studies

Signature Innovations

  • Algorithm: Time-Aware Gaussian Process Regression for non-uniformly sampled sediments

  • Publication: "Deep Learning the Geodynamo: PSV Prediction Across Polarity Transitions" (Science Advances, 2025)

  • Award: 2024 AGU Paleomagnetism Young Scientist Medal

Optional Customizations

  • For Academia: "Established new PSV master curves for Southeast Asia (10–50 ka BP)"

  • For Industry: "Our models reduced drilling risks by 30% in North Sea paleo-reservoirs"

  • For Media: "Featured in NOVA’s ‘Magnetic Mysteries’ documentary
