My laboratory develops ultrasonic beamforming and image reconstruction methods. A current focus in our lab is the development of methods that improve the quality of ultrasound images in the difficult-to-image patient population. For example, my lab has developed a differentiable beamforming technique that estimates the local sound speed to correct for distortion in the ultrasound image. We have also adapted the differentiable beamformer to solve other problems in ultrasound imaging, such as estimation of the array shape for flexible ultrasound arryas. Often, we attempt to build these imaging methods into real-time imaging systems in order to apply them to clinical applications. Another focus of my laboratory is ultrasound molecular imaging, where we used targeted microbubbles to image the molecular signatures of disease. In this project, we have developed nondestructive real-time molecular imaging techniques alongside unique targeted contrast agents for the purpose of early detection of cancer and other diseases. Other small projects in my lab often involve ultrasonic beamforming and image reconstruction in new ways to enhance other areas of ultrasound research, such as drug delivery and passive cavitation mapping.
