About

Research Activities

My research is principally focused on the development and investigation of new, low cost methods for arbitrarily shaping acoustic wave-fronts in 3-D. Utilising, for example, the photoacoustic effect or acoustic lenses in conjunction with single element transducers. This enables the generation of complex spatial-temporal distributions of acoustic pressure in 3-D which have applications across a diverse range of areas in biomedical acoustics. For example, in ultrasound neurostimulation the ability to precisely shape the field allows for skull induced wave-front aberrations to be corrected and for multiple neurological sites to be simultaneously targeted.
