I am an attending physicist emeritus and Director of the Postdoctoral Training Program and the Medical Imaging Physics Residency Program in the Department of Medical Physics.

I have been very active in teaching various aspects of medical imaging physics to radiology residents, radiation oncology residents, medical physics residents, and graduate students for more than 45 years. I am also the Associate Program Director of the Therapeutic Medical Physics Residency Program. I hold a New York State license as medical physicist in diagnostic radiology.

My research interests have been in the areas of dosimetry and image-quality evaluation in radiography/fluoroscopy, mammography, and computed tomography. I am certified in radiological physics by the American Board of Radiology and am a fellow of the American Association of Physicists in Medicine (AAPM), the American College of Medical Physics, the American College of Radiology, and the Health Physics Society. I am a Distinguished Emeritus Member and have served as scientific committee chair and member of the Board of Directors of the National Council on Radiation Protection and Measurements. I am a past president of the AAPM, which has honored me with the Edith H. Quimby Lifetime Achievement Award.

I received my PhD in nuclear physics from the University of Wisconsin, Madison.
