David Orrell, Ph.D., received his doctorate in mathematics from the University of Oxford. His work in the prediction of complex systems has been featured in New Scientist and the Financial Times, and on BBC Radio, ABC Radio (Australia) and NPR. His theory that errors in weather forecasts are due not to chaos (the “butterfly effect”) but to model error stirred up a storm of debate in meteorological circles. He now conducts research in the area of systems biology. He lives in Vancouver, British Columbia.
