Research Interests

Dr. Helfield’s research focuses on the physics of microbubbles for use in a wide array of ultrasound diagnostic and therapeutic applications.  In particular, his interests include nonlinear microbubble oscillation dynamics and scattered emissions – an improved understanding of which is of central importance for furthering agent design efforts and optimizing imaging and treatment strategies for cancer and cardiovascular diseases.  His current emphasis at the Center for Ultrasound Molecular Imaging and Therapeutics is focused on understanding the physical mechanisms involved in ultrasound-stimulated microbubble sonoporation, a strategy that employs the ultrahigh-speed UPMC-Cam imaging system to examine the oscillation characteristics of individual microbubbles adjacent to live endothelial cells.
