Alexander Refsum Jensenius (BA, MA, MSc, PhD) is a music researcher and research musician working in the fields of embodied music cognition and new interfaces for musical expression. He studied music, mathematics and informatics at the University of Oslo. Exchange studies at CNMAT, UC Berkeley, inspired him to complete a master's thesis in music technology, followed by a master's degree in art and technology at the Chalmers University of Technology in Gothenburg. He specialised in methods for studying and interacting with music-related body motion during his PhD, with several long research visits to IDMIL, McGill University. An active member of the international computer music community, Alexander organised the NIME 2011 conference and is currently chair of the NIME steering committee. Although mostly involved in scientific activities at the moment, he still performs on keyboard instruments and live electronics in various constellations, including the Oslo Mobile Orchestra.
