I’m Joe Bunster.

I study how models make decisions—and how to tell when we can trust them.

My background is in mathematics and financial model risk. Today, I work on AI reasoning and evaluation for Meta on contract, and build Regime Alpha, an independent portfolio research platform.

01 / Current work

AI reasoning & quantitative finance.

Two areas of focus, connected by an interest in uncertainty, model reliability, and better decisions.

Professional research · Meta, contract

AI reasoning & evaluation

I examine how AI models reason through mathematics and STEM problems: whether the logic holds, the assumptions are sound, and the evaluation data is reliable.

Independent research · Founder

Regime Alpha

I’m building a platform to understand how portfolio risk and diversification change across market conditions, with clear assumptions and results that can be inspected.

02 / Research foundations

The mathematics behind my work.

My thesis projects explored financial decisions under uncertainty. They shaped my interests in probability, optimization, and how models behave as conditions change.
