Chris Nash is a professional programmer and composer, and currently Senior Lecturer in Music Technology (Software Development for Audio, Sound, and Music) at the University of the West of England (UWE Bristol, UK). He completed his PhD on music HCI at the University of Cambridge, looking at theoretical and analytical methods for modelling and designing interfaces for composition, supported by a longitudinal study of over 1,000 DAW users, empirically investigating user experience with respect to flow, learning, virtuosity, creativity, and liveness. His current research projects focus on digitally-supported amateur musicianship and learning, and end-user programming for music. Around his research, he is the developer of the award-winning reViSiT audio software, and has written music for TV and radio, including the BBC.
