// the map is not the territory
I study how people decide and capital moves, then build tools for the messy parts.

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.
Ready. Use the terminal if you like; every destination is also an ordinary link.

Quantum Computing in the Global Energy Landscape
For four months, our six-person team asked where quantum technologies might actually matter to the energy industry—and how soon. A common three-part framework let us compare six applications without pretending that technical promise and commercial readiness were the same thing.

Renewable Energy Project Finance Modeling
A set of individual assignments built from a redacted wind-project case: contract reviews, tax exercises, and a financial model linking operating cash flow, PTCs, sculpted debt, and P50/P99 cases.

I supported Lisa Sachs's graduate course on how climate finance is built and constrained: blended and concessional capital, sovereign debt, carbon markets, the UNFCCC system, and the cost of capital in emerging markets.

REPF Agent

An early research prototype testing whether PPA terms can be extracted reliably from public documents. Model validation, IRA tax-equity review, and cited investment-memo drafting belong to the hoped-for V1—not the product that exists today.

resume-tailor

A small tool that rewrites only the bullets in a LaTeX résumé for a particular job—and refuses to invent a better past. I built it after spending too many recruiting-season evenings making the same careful edits by hand.

A writing workspace that begins with notes rather than a transcript. It helps turn meetings, fragments, and audio into structured bilingual documents while preserving the memory of a project across time.

about
> cat ./about.md
I took the long way around.
I was born in Zibo and studied behavioral science. Four years left me with one stubborn question for almost everything:
what exactly is going on here?
It turned out to be the right question for finance, too. A model is a story about the future with its claims hidden in assumptions. I moved toward climate finance because self-deception is especially costly there: the commitments are large, the horizon is long, no one knows for certain, and someone still has to live with each decision.
What holds my attention, in the end, is the act of looking: staying with a thing until it stops appearing inevitable. I would rather understand one thing properly than have an opinion about everything.
