K. Stephen Brown is a biostatistician, Professor and a former Chair of the Department of Statistics and Actuarial Science, and Director of Biostatistics at the Propel Centre for Population Health Impact at the University of Waterloo. He also holds a cross-appointment in the School of Public Health and Health Systems. His interests include design and analysis of cluster-randomized prevention trials, correlated discrete response data, generalized linear models, statistical consulting, and statistics education. Dr. Brown has studied the design and analysis of smoking prevention program trials since the first randomized trial of the Waterloo Smoking Prevention Project (WSPPI) began in 1979. He was involved with a seven-year longitudinal, randomized trial (WSPP3) involving approximately 6000 students in 100 elementary schools in South Western Ontario that ran from 1990 – 1996 and was principal investigator on a randomized trial (WSPP4) examining whether a technical assistance package offered to secondary schools will increase their use of effective tobacco use control interventions and, subsequently, reduce teen smoking rates. He was an author of the Technical Reports of the 1994 and 2002 Health Canada Youth Smoking Surveys, and has been a co-investigator on the biennial national Youth Smoking Surveys from the 2004/2005 survey to the present (2012/2013).

He was a co-principal investigator on a the Impact study, a CIHR funded national study that investigated the role of individual, school program and policy, and community characteristics on adolescent tobacco use, and is currently a co-investigator on the COMPASS study, a longitudinal study of high-school aged students that will investigate the role of individual, school and community factors on behavioural factors including smoking, physical activity, healthy eating and other drug use. In addition, he is involved with several studies on the use of social media to increase the reach and effectiveness of 1-800 lines for smoking cessation.
