Stefan Östersjö is professor of Musical Performance and Head of subject at Luleå University of Technology. He received his doctorate in 2008 for a dissertation on interpretation and contemporary performance practice, and since then he has been engaged in senior research projects in Sweden (Two projects funded by the Swedish Research Council and one currently running funded by MAW), Belgium (as a Research Fellow the Orpheus Institute since 2009) and the UK (funded by the AHRC). He became a research fellow at the Orpheus Institute in 2009 and is still active there, currently in a research cluster concerned with subjectivity in musical performance, the final results of which will be published at the end of 2019, primarily in the form of two edited books. His research interests lie primarily in the development of inter-disciplinary collaboration, and the possibilities for method development and the creation of new knowledge through the interaction between musicology, music ethnology (such as in the ongoing MAW project), music psychology, music education and computational approaches, and specifically with an interest in the role of artistic research in such method development.
