The Physical Acoustics Lab (PacLab) is focused on the physics of sound generation, detection, and propagation in the context of underwater sound, industrial ultrasonics, and biomedical acoustics. A particular emphasis of our portfolio is the physical, chemical, and biological effects of acoustic cavitation. This includes sonochemistry, and both single and muiti-bubble sonoluminescence. Another important aspect of our ongoing work has to do with photo-acoustics and acousto-optics, that is, the interaction of light and sound. We have several projects ongoing in this area as well as in partnership with the Rosalind Franklin Institute and Oscar-Suzhou Centre for Advanced Research.
