speaking writing consulting book tool not-knowing

I’m a speaker, consultant, author, toolmaker, and strategy professor at UCL.

I’ve spent over a decade researching the difference between risk and uncertainty — I’ve now broadened my scope to explore the wider range of types of not-knowing that we face.

My speaking, consulting, and writing are all aimed at helping leaders and their organizations understand uncertainty and design themselves to flourish in it.

I’m currently a fellow of the Singapore Government’s Centre for Strategic Futures, and a research fellow at the Future of Life Foundation’s programme on AI for human reasoning, at the Ethereum Foundation’s protocols research programme, and at MOD./University of South Australia.

Here’s what I’m doing now-ish.
