Dr. Leigh Turner’s primary research addresses ethical, legal, and social issues related to companies selling unproven and unlicensed “stem cell treatments.” He is the lead author of the Cell Stem Cell article, “Selling Stem Cells in the USA: Assessing the Direct-to-Consumer Industry” - the first empirical study to systematically document the proliferation of “stem cell clinics” within the U.S. Turner has been published in such journals as Regenerative Medicine, Perspectives in Biology and Medicine, Journal of the American Medical Association, and The Lancet Respiratory Medicine. His scholarship on unproven stem cell interventions involves rigorous empirical analysis of the U.S. direct-to-consumer marketplace for these technologies, addresses ethical concerns related to this industry, and identifyies regulatory steps to take to provide more effective oversight.
Turner’s secondary research examines ethical issues and policy concerns related to “medical tourism” and globalization of health services. He studies ethical and social dimensions of health-related travel and evaluate efforts to promote development by establishing national and regional “bioeconomies.” His research in this area has resulted in a co-edited volume, Risks and Challenges in Medical Tourism: Understanding the Global Market for Health Services, twenty-five peer-reviewed articles, ten book chapters, and thirty-eight presentations. His future work will address ethical issues and public policy concerns related to health-related travel.
Turner previously served as an Associate Professor, William Dawson Scholar, and Graduate Program Director in the Biomedical Ethics Unit at McGill University. Turner also functioned as a clinical ethicist at McGill University Health Centre. From 1998-2000 Turner was an Assistant Professor at the University of Toronto Joint Centre for Bioethics and clinical ethicist at Baycrest Centre for Geriatric Care and Sunnybrook Health Sciences Centre.
Turner received his PhD from the School of Religion & Social Ethics at the University of Southern California.. Turner has been a visiting scholar or fellow at the Brocher Foundation, Institute for Advanced Study, Institute for the Medical Humanities at the University of Texas, Radboud University Nijmegen, and the University of Toronto Munk School of Global Affairs.
