Meet our Lab Director

Stephen P. Lewis, PhD (he/him)

Lab Director

Dr. Lewis is a Full Professor in the Department of Psychology and Research Leadership Chair at the University of Guelph.

His research focuses on self-injury and related mental health difficulties, with an emphasis on fostering resilience and advocating for individuals with lived experience. Central to these efforts is giving a platform to lived experience voices. Dr. Lewis is not only committed to effecting change through research but also via anti-stigma and outreach initiatives that challenge dominant narratives about what it means to live with mental health difficulties. To this end, Dr. Lewis has given a TEDx Talk, participated in various speaking engagements, and published several narratives (e.g., in the Canadian Medical Association Journal), commentaries, and calls-to-action papers advocating for greater inclusion of lived experience voices in all aspects of research and applied psychology. Along these lines, a primary aspect of his work involves addressing self-injury stigma and supporting individuals who self-injure. Dr. Lewis has published extensively in these areas, with well over 100 publications in scholarly journals, numerous book chapters, and two books including the newly published “Understanding Self-injury: A Person-Centred Approach”.

Dr. Lewis regularly conducts media interviews and podcasts on self-injury. Indeed, our team’s work has been featured in major news outlets worldwide (e.g., The New York Times, Time, CBC, Good Morning America, The Toronto Star, CNN, BBC). Dr. Lewis is an original member of the International Consortium on Self-injury in Educational Settings (ICSES) and Past President of the International Society for the Study of Self-Injury (ISSS). During his tenure as ISSS President he spearheaded and presently chairs a special interest group focused on lived experience concerns. Dr. Lewis is also Co-Founder and Co-Director of Self-injury Outreach and Support (SiOS: www.sioutreach.org). SiOS has been accessed in over 180 countries globally and is the first international non-profit initiative providing current information and resources about self-injury to individuals with lived experience of self-injury and those who support them.

Although passionate about research, teaching, and mentoring students, he places great value in a proper work-life balance. This includes spending time with his family (and two young children!), cooking and trying new recipes, taking on new challenges at the gym, maintaining an active lifestyle, doing crosswords, and writing.

Meet Our Team

All of our graduate students have published peer-reviewed articles and presented their research at national or international conferences. Some have also co-authored book chapters and taken part in other lab-related work (e.g., co-presenting workshops, engagement in outreach, work with community partners). To date, all graduate students in the lab have received external funding (e.g., CIHR, SSHRC, OGS) at the MA and PhD levels. All students have also successfully secured competitive predoctoral internship opportunities as a part of their clinical training. Although research involvement is certainly encouraged, it is recognized that graduate students have different career aspirations. Accordingly, the kinds of experiences students receive are tailored to their individual goals and’ needs.
