Research Interests

My primary research interests lie in the general area of biomedical acoustics. Among the specific
topics that we are currently investigating are:
1. the use of high intensity focused ultrasound (HIFU) to reduce or stop clinically significant
hemorrhage from individual blood vessels and solid organs;
2. the use of controlled fields of cavitation bubbles to improve HIFU therapy for solid tumors;
3. the physical responses and biophysical effects of ultrasound contrast agents, i.e.,
microbubbles/microparticles, during preclinical and clinical diagnostic ultrasound examinations;
4. the effect of acoustic nonlinearity on predictions of temperature rise made using the soft-tissue
thermal index (TIS) vs actual temperatures in tissue phantoms.
This work involves close collaboration with colleagues at Boston University, the University of Rochester
and the University of Washington, as well as several commercial firms.

In the future, our group will join an international group of researchers to develop an engineered system
for image-guided HIFU therapy. The “engineered system” concept involves a multi-disciplinary
integration of science and technology applied to complex problems. The final engineered system will
combine HIFU therapy, ultrasound imaging, cavitation monitoring, and control capabilities in a single,
integrated treatment device.
