Maarten Vansteenkiste, Ph.D, is a full professor since 2014 in the Department of Developmental, Personality, and Social Psychology at Ghent University. Since his research internship at the University of Rochester, collaborating with Prof. Dr. Ryan and Prof. Deci, the founding fathers of Self-Determination Theory (SDT), he has substantially contributed to the extension, refinement, application, and dissemination of this framework, both in collaboration with these founding fathers (Vansteenkiste & Ryan, 2013; Vansteenkiste, Ryan, & Soenens, 2020), but also independently from them, thereby establishing his own line of scientific work. His work addresses novel topics in the motivational literature, such as the study of motivational profiles, individuals' multiple reasons for lacking motivation, the interface between psychological and physiological needs, and the development of a more fine-grained and holistic understanding of how different (de)motivating practices of socializing agents (e.g., teachers, parents, coaches) relate to each other. Further, his work is not limited to the development of SDT as such but extends to the motivation literature more broadly as he has written theoretical reviews and book chapters that deal with the interplay between SDT and motivational interviewing, achievement goal theory, and expectancy-value theory. Together with his long-standing colleague and friend Bart Soenens, he has written the Dutch handbook ‘Psychological vitamins for growth’ (Vansteenkiste & Soenens, 2015). A practice-friendly Dutch book entitled ‘Motivating coaching in youth sport’ that translates the basic principles of SDT to sports came out in 2017 (Aelterman, De Muynck, Haerens, Vande Broek, & Vansteenkiste, 2017).
