I study how capital moves toward the climate transition — the mechanisms, the incentives, and the stories we tell about risk. Before Columbia, I read behavioral science and psychology at Duke and Duke Kunshan, where I learned to take human behavior seriously as a unit of analysis. On the good days I'm also a photographer.

Quantum Computing in the Global Energy Landscape
A four-month technoeconomic brief for Wood Mackenzie's research desk on where quantum computing will — and won't — actually move the needle for energy. Six applications (grid optimization, nuclear R&D, battery chemistry, enhanced solar, energy finance, quantum sensing) scored on a three-axis matrix. Two presentations at Wood Mackenzie, a dozen industry interviews, and one phantom client lead who only ever appeared on Zoom.

Renewable Energy Project Finance Modeling
A full cash-flow model for a wind farm project — debt sculpting, PTC/ITC tax-equity structures, P50/90/99 production scenarios, sensitivity tests, and an EPC-aligned term sheet draft.

International Climate Finance — TA
One of two TAs for Lisa Sachs's graduate course on the architecture of climate finance — blended and concessional capital, debt sustainability, carbon markets, the UNFCCC framework, and the cost-of-capital determinants that drive capital allocation in emerging markets.

An AI rewrites the bullets in a LaTeX résumé to match a specific job description — without making things up. I built it during the SIPA on-cycle market when every tailoring round took an hour by hand. Pairs with Claude Code (via `claude -p`) or any LiteLLM-compatible model.

The long way around.

I trained as a behavioral scientist. Four years of learning to ask:

what exactly is going on here?

That same question turned out to be right for project finance, too. A pro-forma is a disguised argument about the future, and the assumptions are the footnotes.

I grew up between Shenzhen, Kunshan, and Durham — three cities that shaped how I read risk, politics, and weather. At DKU I spent my second year analyzing 300k Puerto Rican legislator tweets in R; at SIPA I now build 40-tab cash-flow models for things that haven't been built yet. Same instinct, different grammar.

Off the clock: Red Lion coffee, a backhand that's finally coming in, and a slowly shrinking list of places I haven't photographed.
