received a BA in Physics from the University of Pennsylvania (1962), and an MS (1964) and PhD (1970) in Nuclear Physics from the University of Wisconsin at Madison. After completing a postdoctoral fellowship in Medical Physics in the Department of Medical Physics at Memorial Sloan-Kettering Cancer Center (MSKCC), he joined the professional staff at MSKCC and rose to the rank of Attending Physicist and Clinical Member. He directed the Diagnostic X-Ray Quality Assurance Laboratory for MSKCC and New York Presbyterian Weill Cornell Medical Center for over 35 y until January 2007 when he was appointed Member Emeritus of MSKCC.

Dr. Rothenberg has been President and Chairman of the Board of the American Association of Physicists in Medicine, a founding Board Member of the Commission on Accreditation of Medical Physics Education Programs (CAMPEP), and Chairman of the Board of Chancellors of the American College of Medical Physics (ACMP). He is a Fellow of the American Association of Physicists in Medicine (AAPM), the American College of Radiology, the ACMP, and the Health Physics Society. In 2007, Dr. Rothenberg received the Quimby Lifetime Achievement Award of AAPM.

He served on the original Mammography Committee of NCRP, that was Chaired by Louis Hemplemann and one of whose members was John Boice. Dr. Rothenberg chaired, SC 72, the Mammography Committee of NCRP that produced NCRP Reports No. 85 and 149 and is a Distinguished Emeritus Member of NCRP.

Dr. Rothenberg has concentrated much of his activity in the areas of quality assurance in diagnostic radiology, mammography image quality and dosimetry, computed tomography image quality and dosimetry, and in the education of radiology and radiation oncology residents, physics fellows and residents, and radiologic technologists. He currently lectures on various aspects of imaging physics to radiology, radiation oncology, and medical physics residents at MSKCC, Weill-Cornell New York Presbyterian Medical Center, Harlem Hospital Center, and Jacobi Medical Center. He is the Program Director of the CAMPEP Accredited Medical Imaging Physics residency program at MSKCC and an Adjunct Professor in the CAMPEP Accredited Medical Physics Graduate Program at Columbia University.
