Introduction
My research includes modelling the evolution of music and understanding how the human brain processes music. I am currently developing new computers (and musical systems) based on biological media. I believe that future computing technology will increasingly interface directly with our bodies (e.g., with the nervous system) and media other than silicon media will be increasingly harnessed to act as computers (e.g., bacteria-based computing).

Orchestration is a compositional practice that consists of writing for several instruments. This process often involves harnessing each instrument's sound to create sonic textures that could not be achieved with a single instrument. These sound fusions are usually sought by composers to express specific perceptual effects. However, the number of po...
