*Development of targeted ultrasound contrast agents for image enhancement (molecular imaging), perfusion imaging, and image-guided drug delivery
*Ultrasound-enhanced transport of drugs and genes across cell membranes
*Ultrasound-enhanced drug activity (i.e. chemotherapy, thrombolytics)
*Tissue response to acousto-mechanical forces (apoptosis, wound healing, gene expression, etc.)
*Ultrasound and polymers:ultrasound-induced release of therapeutics from polymeric biomaterials and modification of polymer structure and/or function due to energy deposition from ultrasound
