Research

My research group first recorded the sounds from single microbubbles. After 20 years of research in the field we have contributed in understanding how a microbubble behaviour in the presence of an acoustic field. This research has matured to deliver signal and image processing solutions for use in animal and clinical imaging. Our current multidisciplinary research focusses in cutting edge super-resolution methods that aim to recover blood dynamics in microscopic detail using ultrasound imaging methods.

Biography

Starting from a degree in Physics at the University of Athens (1992) and then onto its applications in Medicine, my education was completed with a PhD in Medical Ultrasound. I have followed that field in the jobs that followed and have developed expertise that span across a range of fields. A common thread in my career has been the desire to improve and achieve the imaging of microvascularity. As a British Heart Foundation Fellow (2007-2011) I put together a research group with the aim to provide an efficient interface with life sciences to translate physics, signal and image processing research into clinical application. Today our focus is to provide cutting edge ultrasound imaging research that draws from other sensing fields like astronomy, radar and sonar
