What I Do

I use mathematics, statistics, software, and artificial intelligence to understand complicated systems—and explain what they mean when people and institutions have to make decisions.

  • Artificial Intelligence

    Machines that choose, predict, classify, and speak—and the institutions that must decide what to do with them.

  • Mathematics & Statistics

    Probability, statistics, numerical methods, and the computational tools that turn quantitative ideas into work.

  • Operations Research & Decision Systems

    Models, constrained resources, complex organizations, and decisions that remain necessary even when the evidence is incomplete.

  • Risk & Resilience

    Hazards, forecasts, resilience, and the stubborn gap between measuring danger and deciding what to do about it.

  • Public Policy & Institutions

    Government, public money, institutional design, and the mechanisms through which collective choices acquire consequences.

  • Software & Open Systems

    Programs, protocols, open systems, and the long practical history of making machines do one useful thing correctly.

  • Teaching & Learning

    Mathematics, technical education, online learning, and the work of helping people understand machinery rather than merely operate it.
