Interests

I study diagnostic and therapeutic uses of ultrasound. I am especially interested in image-guided therapy applications where therapeutic ultrasound is guided by ultrasonic imaging or combined with another imaging modality, such as MRI.

Projects

My lab focuses on diagnostic and therapeutic applications of ultrasound with emphasis on image-guided therapy and drug delivery. Toward this goal, we use micron-sized encapsulated bubbles (microbubbles) to target diseased vasculature and develop algorithms to specifically image these bubbles with ultrasound. Under the right ultrasound conditions, these microbubble contrast agents can also locally enhance vascular permeability, allowing them to act as therapeutic agents as well. Ultrasound can also be used to noninvasively apply heat for focal ablation or activation of temperature-sensitive drugs, and we have an ongoing project where we are performing ultrasonic heating under MR-guidance.
