Researcher

Brian D. Ripley

Brian D. Ripley is a statistician whose work applied neural networks and machine-learning methods to statistical pattern recognition. He earned a Cambridge PhD and held posts at Imperial College, Strathclyde and Oxford. He co-authored Modern Applied Statistics with S-Plus, published research on neural-network classification, wrote Pattern Recognition and Neural Networks, and contributed to R. In 2026, he was named a Rousseeuw Prize laureate; as of October 2026, he is an Emeritus Professor of Applied Statistics at Oxford.
