Sune Vork Steffensen is an Associate Professor, and Director of the Centre for Human Interactivity at the University of Southern Denmark (Odense Campus). In 2008 he took the initiative of forming a research group that in 2012 became the current Centre for Human Interactivity. His field of research includes ecological linguistics, distributed cognition, and human interactivity. For more than a decade he has contributed to the development of ecological linguistics through numerous publications, including joint work with Claire Kramsch. His current research combines interaction analysis, ecological linguistics, and situated, distributed, and systemic approaches in cognitive science. He is one of the pioneers of cognitive event analysis, i.e., the study of how short-scale interbodily dynamics, constrained by large-scale, evolutionary, developmental, and sociocultural patterns, enable agents and systems to achieve results. His main empirical interest is interactivity in organizational settings (primarily within the health sector), e.g., expertise, decision making, and problem solving in complex sociocultural environments. Sune is treasurer of the International Society for Interactivity, Language, and Cognition.
