Core Expertise

As a Volcanic Risk Mitigation Strategist, I develop AI-driven emergency path planning systems to optimize evacuation and resource allocation during volcanic ash dispersion events. My work integrates atmospheric transport modeling, multi-agent simulation, and critical infrastructure resilience to protect lives and aviation safety during eruptions.

Technical Capabilities

1. Dynamic Ash Dispersion Forecasting

• Hybrid Modeling: Combines WRF-Chem simulations with satellite-based lidar (CALIPSO) to predict ash cloud trajectories at 1km resolution

• Uncertainty Quantification: Uses ensemble Kalman filtering to provide probabilistic threat maps updated hourly

2. Evacuation Path Optimization

• Adaptive Routing Algorithms:

  • AshAvoid system dynamically reroutes flights/vehicles based on real-time SO₂ monitoring

  • Integrates road network fragility models to identify ash-free evacuation corridors

• Infrastructure Protection:

  • Prioritizes power grid substations and hospitals in shelter-in-place protocols

3. Cross-Border Coordination

• Game-Theoretic Frameworks:

  • Models airline diversion decisions as non-cooperative games to prevent airspace congestion

  • Developed ash plume bargaining protocols for neighboring countries' airspace management

Impact & Collaborations

• Major Deployments:

  • Lead architect for ICAO's European Volcanic Ash Contingency Plan

  • Optimized 2023 Ruang eruption responses, reducing aviation losses by $120M

• Open Tools:

  • Released VAPOR (Volcanic Ash Path Optimization Resource) toolkit

Signature Innovations

• Algorithm: Pareto-Optimal Ash Diversion (POAD) for multi-objective route planning

• Publication: "Machine Learning the Taupō Caldera Threat Cascade" (Nature Communications, 2024)

• Award: 2024 AGU Natural Hazards Focus Group Prize

Optional Customizations

• For Aviation: "Reduced false airspace closures by 55% through probabilistic thresholds"

• For Government: "Our models informed Indonesia's new volcano watchlist criteria"

• For Media: "Featured in NatGeo's 'When Mountains Breathe Fire'"
