Christopher Russell, Ph.D. is a psychologist and Director of Russell Burnett Research &

Consultancy Ltd (RBRC), a contract research organization that specializes in the design,

conduct, and reporting of perception and behavioral studies of the potential population health

risks and benefits of candidate tobacco harm reduction (THR) products, such as ENDS,

heated tobacco products, and modern oral tobacco products. RBRC designs studies to

characterize adults’ use and perceptions of new tobacco products, longitudinal tobacco

product use transitions, and understanding of product labels, labelling, and marketing

materials. Results of these studies help to inform PMTA, MRTPA, and other applicable

regulatory assessments of the potential impact of candidate THR products on future tobacco

use behavior and population health.
