Ian Brown
Head of Group R & D
Welcome to Research & Development at British American Tobacco, where you will find an overview of our current research and development programmes, research data and recently published papers and posters.
Cigarette smoking is a cause of serious and fatal diseases, so our research and development activities are principally focused on better understanding the mechanisms of harm caused by tobacco use and on developing potentially less harmful products which address this issue. The science of tobacco harm reduction is complex, extremely challenging and spans many scientific disciplines. We have significantly expanded our research capabilities and expenditure over the past few years to reflect the importance we place on work in this area.
We welcome your comments on this website and are pleased to discuss our science or possible collaboration with other scientists working in related areas.

British American Tobacco are currently recruiting for a variety of positions within the analytical sciences function. Specifically, we are looking for scientists with a wide range of experiences to join the novel method development and special analysis team located at our Group Research and Development Centre in Southampton, UK.

There are over 5,000 known tobacco smoke constituents, of which approximately 150 are identified toxicants. It is important to be able to accurately measure these toxicants for current, future and novel products.

The process of smoking a cigarette varies from smoker to smoker, the Tar yield will vary depending on the puff volume, puff duration and number of puffs drawn on the cigarette. Smoking behaviour helps us understand how individual smokers use their product.
