Dr. Ehsan Samei, PhD, DABR, FAAPM, FSPIE is a tenured Professor of Radiology, Medical Physics, Biomedical Engineering, Physics, and Electrical and Computer Engineering at Duke University, where he also serves as the Director of Carl E. Ravin Advanced Imaging Laboratories and the founding Chief of the Clinical Imaging Physics Group. He is certified by the American Board of Radiology, and is a Fellow of the American Association of Physicists in Medicine (AAPM), and the International Society of Optical Engineering (SPIE). He was the founding Director of the Graduate Studies of the Duke Medical Physics Graduate Program, and the co-founder of the Society of Directors of Academic Medical Physics Programs (SDAMPP). He has held senior leadership positions in the AAPM, the SPIE, and SDAMPP. He is a Councilor of the National Council of Radiation Protection and Measurements (NCRP), and a Distinguished Investigator of the Academy of Radiology Research. Dr. Samei’s interests and expertise include x-ray imaging, theoretical imaging models, simulation methods, and experimental techniques in medical image formation, analysis, assessment, display, and perception. His current research includes methods to develop image quality and dose metrics that are clinically relevant and that can be used to design and utilize advanced imaging techniques towards precise interpretive and quantitative performance. He further has an active interest in bridging the gap between scientific scholarship and clinical practice, in the meaningful realization of translational research and in clinical processes that are informed by scientific evidence. While he works across most diagnostic imaging modalities, his main modalities of interest are CT and Tomosynthesis for breast, lung, and abdominal imaging applications. He has been the recipient of 29 extramural grants from the US government, private foundations, and medical industry, and has 700 scientific publications including 190 referred journal articles.
