Systems & AI · Complex Risk · Quantitative Analysis · Strategic Judgment
I solve consequential problems where systems, risk, quantitative analysis and strategic judgment meet.
I help institutions and investors understand difficult exposures, design the systems needed to analyze them, and act on conclusions that can withstand scrutiny.
Four capabilities. One integrated approach.
Systems & AI
I design analytical and decision systems that make complex domains explicit, testable, and auditable.
Complex Risk
I build, repair, and independently challenge risk frameworks across institutions, markets, portfolios, and special situations.
Quantitative Analysis
I use physics, statistics, valuation, and portfolio methods to turn difficult financial questions into tractable models.
Strategic Judgment
I help senior decision-makers understand what matters, what may be missing, and what action the evidence supports.
What sets me apart is the combination.
Each capability stands on its own. The distinctive value is the ability to bring all four to the same problem.
