Dr Paul Brown

Paul is a former Statistics Manager at Which? and has worked as their chief external statistical consultant for over ten years. He has a PhD in pure mathematics and two other higher degrees in mathematics and applied statistics. With more than 20 years experience in the field, he has developed numerous statistical methodologies, algorithms and applications for the various companies he has worked for, many of which are still being used regularly today. Paul has a proven ability to apply his in-depth knowledge of theoretic mathematics and statistics to solving problems in the real world. This includes building sophisticated, interactive models, enabling clients to control and optimize multi-million pound marketing campaigns.


Outside of work, Paul can often be found cheering (or shouting) at the TV whenever Spurs are playing. To relax, he likes spending time with his family, gardening, playing the piano and getting involved in his local community.

Highly technical, he is a specialist in translating business requirements into technical specifications to extract maximum value from the vast array of available data sources.

When he’s not immersing himself in data, Graham loves spending time with his family, and enjoys watching films, playing guitar, eating Indian food and lifting weights, but not all at the same time.
