How capital
moves
—and why.

I keep returning to the seam between the paper version of a thing and the way it behaves in the world: what people do outside the model, where money moves inside an institution, and who finally makes the decision. Behavioral science and climate finance look far apart. To me they ask for the same discipline: don't take a system at its own description. Watch how it works, then decide what to believe.

A wind model, and what it cannot answer.

The course gave us redacted documents from a real wind project. My individual model joined generation, operating cash flow, debt constraints, and equity returns into one chain of consequence.

Beyond the résumé

I took the long way around.

I spent four undergraduate years studying behavioral science. It did not give me a formula for people. It taught me to face a messy situation, resist the quick explanation, and ask: what is actually happening here, and how could we know?

Project finance turned out to reward the same habit. A model appears to calculate, but it is always making an argument about the future; the consequential claims are often tucked into the quietest assumptions.
