About Me

I am a scientist, writer and broadcaster

I am an Australian scientist, living half the year in England and half in Australia (guess which half!). I specialize in food, biophysics, and nano-engineering, although I have also been involved in mining engineering, fundamental physics, future forecasting and philosophy. In the late 1990s, while maintaining my activity in many of these areas, I switched my focus to writing, speaking and broadcasting to help make science accessible and more an integral part of our culture, primarily by showing how scientists think about the problems of everyday life.

I have sometimes made media headlines through light-hearted projects along these lines. These projects have included the physics of biscuit dunking (which led to the award of an Ig Nobel Prize at Harvard University), the absorption of gravy by a roast dinner (which led to my being voted by The Times as “an enemy of the people”), whether hot or cold water freezes faster in a bird bath in winter (demonstrated live on the BBC Radio 4 “Today” programme), the formula for the perfect cheese sandwich, and how best to stir porridge. I have twice been a speaker at London’s Royal Institution, and I am a regular speaker at the annual Oxford Symposium on Food and Cookery, where I am also a member of the advisory board. My best-selling book How to Dunk a Doughnut: The Science of Everyday Life (2002) was translated into eleven languages, and resulted in my election as “Science Writer of the Year” by the American Institute of Physics. I have also made many radio and television appearances worldwide, including three series for BBC Radio 4 (The Science of DIY, The Sweet Spot and Redesigning the Body), and many programmes for Radio National in Australia. I have also written numerous feature articles for newspapers and magazines, including two series for The Guardian (co-authored with Peter Barham) on The Science of Cooking.

More recently, I have focused my attention on serious social and global issues, first with a book Weighing the Soul: The Evolution of Scientific Ideas (2004), which was concerned with showing how science actually works, and then with a trilogy about the role of science in addressing the major problems that we now face: Rock, Paper, Scissors: Game Theory in Everyday Life (2008) (on the problem of cooperation); The Perfect Swarm: The Science of Complexity in Everyday Life (2009) (on making decisions in complex situations); and Crashes, Crises and Calamities: How We Can Use Science to Read the Early-Warning Signs (2011) (on predicting and dealing with sudden and sometimes catastrophic change in economies, nature and society).

These books led to invitations to become actively involved with groups working in these areas. I have written an invited chapter in a textbook on counseling and psychotherapy (on the role of game theory in human interactions), and have been working for the past decade on understanding and coping with the interconnectedness between global threats such as climate change, loss of biodiversity, and increasing disparities in wealth and living standards. This work has been in collaboration with the Swiss-based International Risk Governance Council, for whom I prepared a major report “Preparing for Future Catastrophes” (2011); Oxford University’s Institute for the Future of Humanity, where Anders Sandberg and I have prepared a major policy review “A Safe Governance Space for Humanity: Necessary Conditions for the Governance of Global Catastrophic Risks” (to appear in Global Policy); economists, sociologists and historians at Doshisha University of Kyoto and The University of Wollongong, Australia on transforming the global economic system (two chapters in “The Kyoto Post-COVID Manifesto for Global Economics – Confronting Our Shattered World” (Springer); and complexity scientists from Binghampton University, New York and the Helmholtz Institute for Functional Marine Biodiversity at the University of Oldenburg, Germany, with whom I am writing an invited review for Nature Sustainability on reassessing sustainability in the light of interconnectedness and complexity.

I continue to complement these more academic endeavours with articles, talks and radio broadcasts (see accompanying list) intended to bring these important issues to public attention.

My Books

My best-selling book How to Dunk a Doughnut: The Science of Everyday Life (2002) was translated into eleven languages, and resulted in my election as “Science Writer of the Year” by the American Institute of Physics.

This was followed by Weighing the Soul: The Evolution of Scientific Ideas (2004), which was concerned with showing how science actually works (although one bookshop misinterpreted the title and put it in the religious section!), and then with a trilogy about the role of science in addressing the major problems that we now face: Rock, Paper, Scissors: Game Theory in Everyday Life (2008) (on the problem of cooperation); The Perfect Swarm: The Science of Complexity in Everyday Life (2009) (on making decisions in complex situations); and Crashes, Crises and Calamities: How We Can Use Science to Read the Early-Warning Signs (2011) (on predicting and dealing with sudden and sometimes catastrophic change in economies, nature and society).
