Peter Dejans is director of the Orpheus Institute, a centre for advanced studies and research in music based in Ghent, Belgium. He founded this institution in 1996. 

Peter received his music training at the Brussels Royal Conservatoire and the Lemmens Institute, Leuven (graduating in choir conducting) and graduated from the Universities of Leuven and Tübingen (Law studies and Postgraduate Studies in Business Economics). Through his leadership of the Orpheus Institute, and high-level involvement in many international networks, he has become a prominent voice for the newly emergent field of artistic research in music. His work remains grounded in the experience of music making. Peter has a wide concert experience with his chamber choir Musa Horti (with several recordings of contemporary choir music), and is often invited as guest conductor by other ensembles, including the Flemish Radio Choir. 

Peter has a strong commitment in many international committees and working groups. He has been the chair of two AEC Polifonia Working Groups focusing on Artistic Research in Higher Music Education in Europe. He has been the co-founder of EPARM (European Platform Artistic Research in Music), which he has been chairing for 9 years (2011-2019). For many years, he was also a member of the ELIA Artistic Research Working Group. 

In 2022 he was awarded a Doctorate honoris causa by the University of Music Freiburg (Germany) in recognition for his services to music.
