Emad Ebbini, PhD

Strategic Advisor

Get to know Dr. Ebbini

Dr. Ebbini received his PhD from the University of Illinois at Urbana-Champaign in 1990. He is currently a professor in electrical and computer engineering at the University of Minnesota Twin-Cities. His research interests are in signal and array processing with applications to medical ultrasound. He is a fellow of the IEEE and has been active in several IEEE societies, conferences and journals. Dr. Ebbini also served as the President of the International Society for Therapeutic Ultrasound (2012 – 2015) in addition to being a founding member of the Society in 2001. He contributed to both diagnostic and therapeutic aspects of medical ultrasound, including optimal array pattern synthesis for imaging and therapy, temperature imaging, nonlinear contrast agent imaging, high-speed parallel imaging.

Dr. Ebbini pioneered the concept of dual-mode ultrasound array (DMUA) systems for image-guided surgery and other noninvasive interventions such as transcranial neuromodulation. His research team at Minnesota recently demonstrated the real-time use of this technology in a preclinical model of hypertension in vivo, where they have demonstrated the feasibility of forming precise thermal lesions in the carotid body. The technology has also been used to successfully target/ablate atherosclerotic plaques in the femoral artery in human patients under license from the University of Minnesota. Most recently, Dr. Ebbini has been collaborating with colleagues from Neurosurgery to investigate the use of ablative and neuromodulatory applications of transcranial focused ultrasound (tFUS), including potential treatment of glioblastoma. His laboratory is currently investigating a number of novel approaches involving 3D imaging, real-time ultrasound thermometry in vivo, and self-focusing arrays in the presence of strongly scattering objects.

Dr. Ebbini has served on numerous consulting and advisory panels for governmental and private organizations, including NIH, NSF, and NASA. He was a charter member of the NIH Biomedical Imaging Study Section-B and he currently serves as a consultant to the FDA Center for Devices and Radiological Health. He has also served as an associate editor/editorial board member for several journals and a guest editor of three special issues on therapeutic ultrasound.
