Performance Studies international (PSi)
PSi is the largest international organisation in the field of Performance Studies. Performance Studies is a field of research that can be better described as an interactive web between multiple disciplines rather than a closely demarcated discipline in itself. Originally branched off from Theatre Studies, in the past decades Performance Studies has developed as an umbrella term for research engaged with a wide variety of topics from the perspective of performance and performativity. The research conducted under this umbrella term is interdisciplinary per definition and is strongly rooted in the interaction between theory and practice. PSi represents this field and stimulates its development among others through the organisation of yearly conferences. These conferences are initiated by PSi’s Board of Directors but are thematically designed and executed by an organisation that changes each year. PSi supports the local organisation through advice and by disseminating know-how.
