Core Expertise

As a Space Weather Data Scientist, I develop machine learning frameworks to detect and classify anomalous pulsations in auroral emissions, bridging magnetospheric physics, time-series analysis, and AI-driven pattern recognition. My work uncovers hidden signatures of space weather events and geomagnetic disturbances through the lens of Earth’s most captivating light phenomena.

Technical Capabilities

1. Multispectral Aurora Monitoring

  • Data Fusion:

    • Integrated All-Sky Imagers (ASI), SuperDARN radar, and Swarm satellite data to track field-aligned currents

    • Developed AuroraNet – A spatiotemporal CNN detecting STEVE (Strong Thermal Emission Velocity Enhancement) events with 94% accuracy

  • Anomaly Typology:

    • Classified 7 subtypes of auroral wave disturbances (e.g., omega bands, flickering arcs)

2. Physics-Informed AI

  • Hybrid Models:

    • Embedded Lorentz force equations into LSTM networks to predict substorm onsets

    • Quantified proton aurora contamination using SHAMISEN spectral libraries

  • Edge Computing:

    • Deployed real-time detection on Arctic field stations (≤500ms latency)

3. Space Weather Applications

  • Geomagnetic Storm Warnings:

    • Correlated pulsating patches with Dst index drops (30–60 min lead time)

  • Satellite Protection:

    • Identified auroral precipitation zones threatening LEO spacecraft electronics

Impact & Collaborations

  • Global Networks:

    • Lead analyst for THEMIS-ASI anomaly alert system

    • Advised ESA on EnVision Venus aurora observation strategies

  • Open Science:

    • Released AuroraDB – Largest annotated dataset of auroral irregularities (12TB)

Signature Innovations

  • Algorithm: Fourier-Wavelet Anomaly Scoring (FWAS) for multiscale periodicity detection

  • Publication: "Deep Learning the Alfvénic Aurora" (JGR: Space Physics, 2025)

  • Award: 2024 AGU Space Weather Early Career Prize

Optional Customizations

  • For Academia: "Discovered 3σ correlation between pulsating patches and plasmaspheric hiss"

  • For Industry: "Our models reduced false alarms by 50% for transpolar flight routes"

  • For Outreach: "Featured in NatGeo’s ‘Aurora Decoders’ documentary"
