David Giraud M.Eng., is a Senior Research Engineer in the Knight Cardiovascular Institute at OHSU. He completed his undergraduate education at the University of Washington in 2008, earning B.S. degrees in physics and applied and computational mathematical sciences. Afterward, he worked as a physicist in the Center for Industrial and Medical Ultrasound at the Applied Physics Laboratory at the University of Washington. His projects included the study of inertial transient cavitation in high-quality-factor resonators at high static pressures using ultra-fast optical imaging and ultrasound contrast agent sizing and shell characterization using modified flow cytometry. He obtained his M.Eng. degree in mechanical engineering at Boston University in 2012 where he studied the use of acousto-optic interaction to monitor tissue ablation produced by high-intensity focused ultrasound. His current responsibilities at OHSU include:

· Development and use of a novel ultra-fast bright-field microscope designed to investigate microbubble cavitation bioeffects induced by ultrasound.

· Investigating catheter-based methods of using ultrasound thermal therapy for cardiovascular disease.

· Supporting investigators who study therapeutic ultrasound for cardiovascular and cerebrovascular disease by characterizing therapeutic microbubbles and calibrating and operating experimental ultrasound equipment.

In his free time, he enjoys skiing and bicycling while exploring the natural beauty of the Pacific Northwest.
