My research aim is to develop new imaging and sensing technologies using acoustic waves at ultrasonic frequencies. Current research projects focus on high frame-rate ultrasound imaging, super-resolution methods, 3D ultrasound imaging, signal processing for biomedical imaging, ultrasound sensor modelling and development.
I have a PhD in Electronic and Electrical Engineering, University of Leeds. As a research fellow, I worked on the development of new transducer technologies and ultra-fast ultrasound imaging. In 2016, I worked at Imperial College London and King’s College London (visiting researcher) on 2D and 3D ultrasound super-resolution imaging, as a postdoctoral researcher. In 2019, I joined LSBU.
I lead the SPE3D (/speed/) Ultrasound research lab: https://sevanharput.github.io/
I am the head of the South Bank Applied BioEngineering Research (SABER): https://www.lsbu.ac.uk/research/centres-groups/bioengineering
