What I keep coming back to is the gap between how things look on paper and how they actually work: how people behave, and how a decision really gets made. That's the thread running from behavioral science to climate finance. The material changed; the habit of watching closely didn't. Mostly I've learned to trust a good question more than a tidy answer.

Quantum Computing in the Global Energy Landscape
A four-month technoeconomic brief on where quantum technologies could create material value in energy, and on what timeline. Our six-person team compared grid optimization, nuclear research, battery chemistry, enhanced solar, energy finance, and quantum sensing through a shared three-axis framework.

REPF Agent
2026 · active · Python · Claude Code
A vertical AI agent for U.S. renewable energy project finance. It parses PPAs, validates sponsor models, checks IRA-era tax equity structures, and drafts IC memos with citations. Phase 0: eval harness on hand-graded public PPA cases, not a product yet.

resume-tailor
2026 · active · Python · LaTeX
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 was born in Zibo, and trained as a behavioral scientist. Four years spent learning to ask one stubborn question of almost everything:

what exactly is going on here?

It turned out to be the right question for finance, too. A pro-forma is really a story about the future, and the assumptions are where the real claims hide. I moved toward climate finance because that's where the question feels most alive. The numbers are large and the uncertainty is admitted rather than hidden.

What holds my attention, in the end, is the watching itself: sitting with something until it stops being obvious. I'd rather understand one thing properly than have an opinion about everything.
