William G. Webster, PhD, whose photo appears on the front cover, is a retired university professor, a former dean, and a person who stutters. The first twenty-two years of his career included being a professor and chair of the Department of Psychology at Carleton University in Ottawa, Canada, where he established an active research program focussed on the brain mechanisms underlying stuttering. The results of that research have been published in journal articles and edited book chapters, have been presented at professional conferences, and form the core of this book. He co-authored with Marie Poulos in 1989 a clinical manual entitled Facilitating Fluency: Transfer Strategies for Adult Stuttering Treatment Programs. In 1991, he was appointed Dean of the Faculty of Social Sciences at Brock University in St. Catharines, Ontario, and in 2002, Director of the School of Communication Sciences and Disorders at the University of Western Ontario (now Western University) in London, Ontario. From 2005 until his retirement in 2016, he was Dean of the Faculty of Health Professions at Dalhousie University in Halifax, Nova Scotia. He has four grown children and resides in Halifax, Nova Scotia, with his wife, Anne.
