      John A. Shepherd, PhD, CCD, is a Professor in the Department of Radiology and the Director of the Breast and Bone Density Imaging Group at the University of California, San Francisco. He is an expert in quantitative breast imaging as well as musculoskeletal imaging using x-ray absorptiometry techniques. Dr. Shepherd received his BS in Engineering Physics from Texas Tech University in Lubbock, Texas, and he obtained his PhD in Engineering Physics from the University of Virginia in Charlottesville, Virginia, followed by a postdoctoral fellowship in Biophysics from Princeton University in Princeton, New Jersey.

      Dr. Shepherd’s research interests involve quantitative imaging methods for tissue composition using x-rays. His mammographic methods are used extensively for research around the world and in the San Francisco Mammography Registry Program. Dr. Shepherd’s efforts are focused on the technical imaging aspects of the measurements of the body composition and the translation of these measurements into different fields of study. He has present and future research projects in the following areas: breast cancer risk and detection using breast density and tissue texture measures; dual-energy x-ray diagnostic mammography for characterizing compositional signatures of cancer lesions; total body protein measures, body shape analysis and metabolic diseases; statistics of quality assurance and quality control for quantitative measurements.

      Expertise:
      Quantitative breast imaging, breast density, bone density, body composition, statistical methods of quality control.

      Specialty:
      Quantitative imaging methods for tissue composition using x-rays, dual-energy x-ray absorptiometry (DXA)

      Professional Interests:
      Body composition, diagnostic x-ray imaging, mammographic density, bone densitometry, dual x-ray absorptiometry (DXA), single X-ray absorptiometry (SXA), quantitative computed tomography, osteoporosis, breast cancer, peripheral bone densitometry, quantitative ultrasound
