R. D. R. G. (David) Orrell

R. D. R. G. (David) Orrell is a mathematician and scientist specializing in how complex systems—like weather, markets, or ecosystems—behave and are modeled. He studies the limitations of predicting such systems accurately due to their inherent unpredictability, and explores ways to improve understanding and decision-making in uncertain environments. Orrell’s work combines mathematics, physics, and economics to analyze risk, modeling errors, and the impacts of randomness, helping us better grasp the challenges in forecasting complex phenomena and managing associated uncertainties.
