Ahmed El Kaffas is a research fellow in the Department of Radiology at Stanford University. His research aims to push the limits of biomedical applications of ultrasound by tackling clinical, translational and workflow challenges through his training and experience in ultrasound engineering and physics, as well as electrical and computer engineering. He has over 10 years of exposure to ultrasound-related research, which include: longitudinal quantitative 3D ultrasound imaging methods, ultrasound tracking and positioning systems, ultrasound numerical modeling, and therapeutic ultrasound in radiation oncology, development of cell mechanic measurement methods to validate ultrasound measurements and multi-modal image registration (ultrasound/MRI and ultrasound/CT). This work has resulted in over 25 peer-reviewed publications, three intellectual property disclosures, and a start-up company of which he is a co-founder in Toronto, Ontario (Oncoustics inc.). As a postdoctoral fellow, he is leading multiple clinical research projects focused on developing quantitative interventional ultrasound techniques that utilize navigation systems for cancer imaging. Through this, he has gained extensive awareness of clinical challenges faced by ultrasound operators for quantitative diagnostics and interventional imaging applications (pioneering 3D contrast-ultrasound cancer treatment monitoring).
