  • ESG- and climate-aligned investment modelling

I sit at the intersection of investment and technology:

  • Build models and pipelines that link physical energy assets (batteries, PEM electrolysers, hybrid storage)
    with financial outcomes (cash flows, risk, ESG metrics, scenario analysis).
  • Work with simulation, optimisation, and machine learning to support decisions in
    energy trading, infra investing, and portfolio risk management.

    • Scenario-based valuation of energy assets (batteries, hydrogen, hybrid storage)
    • ESG risk analytics, carbon accounting, EU Taxonomy & SFDR alignment
    • Portfolio stress testing, VaR, Sharpe ratio, factor and sensitivity analysis
  • Technology & Modelling

    • Multiscale electrochemical modelling (PEMWE, Li-ion, HESS)
    • Physics-based + data-driven hybrid models (COMSOL, PyBaMM, Simulink)
    • Scientific ML: PINNs, surrogate models, GAN-based augmentation

Finance & ESG

  • Portfolio analytics: VaR, CVaR, stress testing, performance attribution
  • ESG reporting: EU Taxonomy, SFDR-aligned metrics, carbon cost modelling
  • Cash-flow modelling for energy projects and structured products
  • Understanding of energy markets (TOU arbitrage, ancillary services, power pricing)

Energy & Engineering

  • PEM water electrolysers, Li-ion batteries, hybrid energy storage systems (HESS)
