I'm a philosopher in the ILLC at the University of Amsterdam. I'm also an external member of the Munich Center for Mathematical Philosophy and CEO and co-founder of DelphiCloud.

I completed my PhD at the Australian National University on the philosophy of probability in 2010, and I have degrees in mathematics and philosophy from the University of Queensland in 2006.

I have held academic positions at the University of Maryland, the Munich Center for Mathematical Philosophy, the Tilburg Center for Ethics and Philosophy of Science, the University of Vienna, the University of Melbourne, the University of Sydney, and the Australian National University.

In addition to being an academic, I've also operated as risk management consultant for the Australian Government and other clients since 2011.

My research is primarily on the philosophical foundations of uncertainty, decision making, philosophical psychology, and social epistemology — with a particular focus on the wisdom of crowds. My company, DelphiCloud, applies this research in the form of software to help our clients make sound probabilistic forecasts in situations of high stakes and extreme uncertainty.

In recent years my reseach focus has turned to the topics of psychedelics and meditation. I believe that by developing a better understanding of these topics we can shed new light on the nature of uncertainty, wisdom, good decision making, and creative problem solving.


My main research interests are the philosophical foundations of uncertainty. One idea that drives a lot of my thinking is that the problem of induction is one of the deepest problems of philosophy and has an enormous practical impact on the everyday decisions we make.

An important consequence of the problem of induction is that there is no privileged epistemic perspective for us to enjoy: that is, there is no single correct way of looking at the world and figuring out what’s going on. It isn’t just that we all have our blindspots and biases; rather, the problem is that we all must have blindspots and biases. In short, black swans are unavoidable.

However, and fortunately, there are things we can do to manage the risks of black swans. Although there is no privileged perspective, some perspectives are clearly better than others in some circumstances, and there are things one can do to improve one’s own perspective. Moreover, in many situations we can combine our different individual perspectives into a superior collective outlook. These observations underly my research in the wisdom of crowds and also the methods of DelphiCloud.

Over the years, I have slowly realised that my fascination with uncertainty is actually a fascination with wisdom. Although my training has been in the Western traditions of analytic philosophy, mathematics, and science, I have found tremendous value in Buddhist philosophy and what it has to say about wisdom. As a result, a lot of my research now is on integrating Buddhist insights into the rest of my work.

Psychedelic Experience

This book presents a systematic and rigorous philosophical analysis of the concept of psychedelic experience based on the latest scientific research into psychedelics and meditation.

A central thesis of the book is that a psychedelic experience is nothing but a mind-revealing experience, which is something that can occur without the consumption of any substances. Indeed, it is argued that the careful and sustained practice of meditation can be a better, safer, and more reliable way of inducing such experiences. It is also shown, based on scientific evidence and philosophical analysis, how psychedelic experiences can be used to improve creative problem solving, probabilistic forecasting, and decision making.
