About the Speaker

John Eisenbrey, Ph.D.
Professor of Radiology
Thomas Jefferson University
John Eisenbrey received his bachelors degrees in Mechanical Engineering and Management from the University of Delaware, followed by his Ph.D. in Biomedical Engineering at Drexel University. He is currently a Professor of Radiology at Thomas Jefferson University in Philadelphia. His lab is funded by federal, industrial, and philanthropic grants and focuses on nonlinear ultrasound imaging, image-guided drug delivery, interventional oncology, and photoacoustic imaging. His group is actively researching emerging ultrasound applications and their translation to clinical care. These areas include nonlinear and volumetric imaging, contrast-enhanced ultrasound in interventional oncology, noninvasive pressure estimation, perfusion estimation, small animal ultrasound, ultrasound-mediated drug delivery, and photoacoustic imaging. Current research project stages span from bench-top experiments to multi-center.
About the Moderator

Klazina Kooiman, Ph.D.
Associate Professor
LabTAU (INSERM), Lyon, France
Biomedical Diagnostics Lab,
Eindhoven University of Technology, Eindhoven, the Netherlands
Klazina Kooiman received the M.Sc. degree with honors (cum laude) in Biopharmaceutical Sciences, specializing in pharmaceutical technology, from Leiden University, Leiden, the Netherlands, in 2000, and the Ph.D. degree in ultrasound contrast agents for therapy from the Department of Biomedical Engineering, Thoraxcenter, Erasmus MC University Medical Center Rotterdam, the Netherlands, in 2011. Following her Ph.D., she held successive academic positions at Erasmus MC University Medical Center Rotterdam, first as a postdoctoral fellow, then as Assistant Professor (2015–2020), and subsequently as Associate Professor (2020–2025) in the Department of Biomedical Engineering, Thoraxcenter. In 2013, she was a visiting scholar at the University of Pittsburgh Medical Center (UPMC), Pittsburgh, PA, USA.
She is currently an Associate Professor at LabTAU (INSERM) in Lyon, France, and at the Biomedical Diagnostics Lab, Eindhoven University of Technology, Eindhoven, the Netherlands. Her research focuses on the theragnostic field of ultrasound-activated microbubbles (1–8 µm) for local drug delivery and ultrasound molecular imaging of cardiovascular disease and cancer. To elucidate the mechanisms of microbubble-mediated drug delivery, she employs multidisciplinary translational approaches at the interface of engineering, biology, and pharmacy.
Her research targets endothelial cells for vascular drug delivery and bacterial biofilms in infective endocarditis, including infections associated with cardiac devices. She is the co-director of the annual European Symposium on Ultrasound Contrast Imaging and co-chair of the Contrast Agents Track of the IEEE International Ultrasonics Symposium. She has served as a board member of the International Society for Therapeutic Ultrasound (ISTU) since September 2024.
