Dean is a composer/improviser, and researcher in music cognition/computation. He founded austraLYSIS, which has performed in 30 countries. His performances on the bass, piano and laptop range from the Academy of Ancient Music to the London Sinfonietta; his improvising collaborations from Ted Curson to Evan Parker. He has extensive experience in contemporary jazz and free improvisation, mainly playing piano and computers, but previously also bass and vibraphone: with Graham Collier Music (1975 until its final recording in 2013), LYSIS and austraLYSIS, the London Jazz Composers' Orchestra, a numerous others from Europe and Australia. Dean’s work is on 50 commercial cds, and many intermedia and installation pieces (with Keith Armstrong, Will Luers, Hazel Smith and others). His creative work centres on keyboard/ensemble improvisation and computer music composition. These merge in his solo MultiPiano Event (live grand piano, real-time audio processing, generative piano, and electroacoustic sound). His research currently focuses on cognition of music and its computational modelling and generation, in relation to pitch, timbre, rhythm, intensity and affect. He edited the Oxford Handbook of Computer Music (2009), and has written five books on music, particularly improvisation. He co-edited the Oxford Handbook of Algorithmic Music (2018), with Alex McLean (then of Leeds University, UK). He has previously, alongside music creation, been a research biochemist and molecular cell biologist, as a professor at Brunel University, UK; and as the foundation director of the Heart Research Institute (in Sydney, Australia). From 2002-2007 he was the Vice-Chancellor and President of the University of Canberra, and also commenced his scientific work in music cognition and computation, which he now continues as a research professor at the MARCS Institute for Brain, Behaviour and Development, Western Sydney University.
