Core Expertise

As a Biogeochemical Systems Modeler, I develop computational frameworks to quantify energy transfer pathways in deep-sea hydrothermal vent ecosystems, integrating thermodynamic principles, microbial metabolomics, and fluid dynamics. My work reveals how chemosynthetic life exploits geochemical gradients to sustain biodiversity in Earth's most extreme environments.

Technical Capabilities

1. Energy Flow Network Modeling

• Multi-Trophic Integration:

  • Built VentFlow – A reaction-diffusion-advection model coupling:

    • Inorganic substrates (H₂S, CH₄, Fe²⁺ gradients)

    • Microbial consortia (ANME-2 archaea, ε-proteobacteria metabolic rates)

    • Macrofauna (tubeworm symbiont energy budgets)

  • Resolved 15+ energy currencies (e.g., ATP, NADH) across 0.1mm–10m scales

2. Extreme-Environment AI

• Data Assimilation:

  • Fused Alvin submersible sensor data (1Hz) with OsmoSampler time-series (monthly)

  • Trained graph neural networks to predict vent community resilience to eruptions (AUC=0.91)

• Autonomous System Design:

  • Co-developed ROV-mounted laser spectrometers for real-time ΔG° calculations

3. Astrobiological Applications

• Enceladus/Europa Analog Studies:

  • Adapted models for putative H₂O₂-based vent systems (published in Astrobiology)

• Resource Mapping:

  • Identified poly-metallic nodule formation hotspots linked to microbial activity
