The DoctorAl Training Network in Sport Ethics and Integrity (DAiSI) is an interdisciplinary network comprised of 5 prestigious universities (KU Leuven (Belgium, lead), Johannes Gutenberg University Mainz (Germany, beneficiary), Norwegian School of Sport Sciences (Norway, beneficiary), Swansea University (Wales, beneficiary), and University of Lausanne (Switzerland, associated partner)) and 8 leading international sport federations, sport organisations and non-governmental organisations: International Olympic Committee (IOC), International Federation of Football Associations (FIFA), Union of European Football Associations (UEFA), United Nations Office on Drugs and Crime (UNODC), World Anti Doping Agency (WADA), International Biathlon Union (IBU), and Athletics Inegrity Unit (AIU). Our research domains include cheating, doping, match-fixing, data protection, sexual harassment and abuse, credibility, reputation and damage-limitation. We examine the problems, identify published and novel solutions, deliver multi-disciplinary research and work with stakeholders to improve policy and guidelines to prevent future harms to sportspersons and organisations. The network provides extensive training and interdisciplinary doctoral education to 13 selected doctoral researchers, recruited impartially from around the world. Every thesis contributes to a coherent programme of research, which takes a three-dimensional approach, at the individual, competition and organisational levels (each of which has its own ethical, legal and social challenges). Our researchers will graduate from the programme with a joint doctorate from at least two leading universities, as well as having gained real-world experience and skills that make them immensely attractive to employers.
