The Experimental Ultrasound and Neural Imaging Laboratory(EUNIL) group develops innovative tools and techniques for applications related to biomedical imaging and neural engineering.

Novel sources for ultrasound contrast include optical absorption, mechanical strain, and electrical current. These techniques have potential applications in a range of biomedical applications from colon cancer to epilepsy.

Ultrasound imaging is functional, high resolution, low cost, noninvasive and non-ionizing, complementing other imaging modalities.
