Backed by a half-century of professional experience, Larry A. DeWerd, Ph.D., is a renowned leader in the field of medical physics. He is known for his expertise in all aspects of radiation metrology, including the calibration of ionization chambers, radiation dosimetry, quality assurance in diagnostic radiology and radiotherapy, and luminescence for dosimetry.
Since 1975, Dr. DeWerd has been sharing his knowledge with students and colleagues at the University of Wisconsin. His success as a visiting assistant professor gained him the opportunity to join the faculty, as he was hired as a clinical assistant professor from 1976 to 1979. Subsequently, he assumed roles as a clinical associate professor and professor of medical physics. Notably, since 1990, Dr. DeWerd has concurrently held the title of director of the University of Wisconsin Radiation Calibration Laboratory, which he started in 1977, and vice president of Standard Imaging Inc., started in 1989, a leading provider of radiation calibration and quality assurance equipment.
Throughout the course of his illustrious career, Dr. DeWerd has exercised his passion for his profession through various affiliations, including the Health Physics Society, the American Association of Physicists in Medicine (AAPM), the American Physical Society, and Sigma Xi, The Scientific Research Society. From 1995 to 1998, he served as president of the Council on Ionizing Radiation Measurements and Standards. Dr. DeWerd also served as president of the North Central chapter of the AAPM from 1990 to 1992. He is also a fellow and Lifetime Achievement awardee of the American Association of Physicists in Medicine. A philanthropist at heart, he contributed to the American Cancer Society as its science chairman from 1986 to 1990.
Dr. DeWerd is often noted for his many writing contributions. He is a contributing author of “Calibration Importance of Ionizing Radiation for Medical Applications in Radiation Therapy and Diagnostic Radiology,” “Entrance Skin Exposure and Mean Glandular Dose: Effect of Scatter and Field Gradient at Mammography,” and “TLD Measurements of in Vivo Mammographic Exposures and the Calculated Mean Glandular Dose across the United States,” among many more. He currently serves as an associate editor for the journals Radiation Measurements and Medical Physics.
