Areas of active research include coherent imaging, including optical-coherence tomography and laser-speckle imaging, fluorescence imaging, and the study of light transport in biological tissue.

Atherosclerosis, a buildup of plaque, can lead to heart disease, artery disease, and chronic kidney disease and is traditionally treated by inserting and inflating a balloon to expand the artery.

Physicists have transformed laser light into a supersolid, marking an entirely new process for achieving this mysterious ...

Ultrasound-activated microbubbles can deliver drugs into cells by forming high-speed liquid microjets that penetrate cell membranes. These microjets, moving at 200 kph, create pores without ...
