My research

I joined the Biomedical Ultrasound Group at UCL as a postdoctoral research associate in November 2014. My research is concerned with the measurement of acoustic fields, particularly therapeutic ultrasound fields, and with the measurement of the acoustic properties of materials.

High intensity focused ultrasound therapy works by inducing high temperatures, cavitation and boiling to destroy diseased tissues. Measurement of the ultrasound fields is challenging under these extreme conditions as the sensitive devices often used to measure acoustic pressure are easily damaged. My recent work, in collaboration with the Photoacoustic Imaging Group at UCL, uses a robust sensor, which can withstand these conditions and measure the pressures generated at the focus of therapeutic fields.
Another aspect of my work is concerned with making comparisons between accurate hydrophone measurements and simulations of acoustic fields made using the k-Wave toolbox.
These simulations also require knowledge of the acoustic properties of the tissues that the ultrasound travels through, so I am also interested in measuring the speed of sound and attenuation coefficient of biological and tissue like materials over the broad frequency and temperature ranges which occur during focused ultrasound therapy.
