Christopher Russell Ph.D. is the Director of Russell Burnett Research and Consultancy Limited (RBRC), a contract research organization that specializes in the design and conduct of perception, intention, and behavioral studies of tobacco and nicotine products. Studies are designed to obtain information about individuals’ use and perceptions of tobacco and nicotine products; understanding of product labels, labelling, and advertising; and intentions to stop, start, and continue using tobacco and nicotine products. The results of these studies help to inform regulatory assessments of the potential impact of new tobacco products on tobacco use behavior and population health.
