Radiology Physics Graduated Residents

  • Education
    PhD, Ryerson University, 2020
    Muhannad successfully completed the Medical Physics residency program in June 2022.Muhannad completed his PhD in the Department of Physics at Ryerson University under the supervision of Dr. Michael Kolios. Muhannad’s doctoral research focused on the use of quantitative frequency analysis and multispectral imaging to improve the capability of photoacoustics imaging to detect structural and biochemical changes red blood cells undergo in response to cancer therapy. Currently Muhannad is excited to gain clinical experience through a diagnostic medical physics residency program at Yale New Haven Hospital.
  • Assistant Professor

    PhD, Johns Hopkins University, 2015
    Kevin was the first resident in the Yale Diagnostic Medical Residency program, starting in February 2019. He successfully completed the program in February 2021. In March 2021, he joined the YDMP faculty. He looks forward to being an active contributor to resident education and experience, and also to delivering high quality services to Radiology and to patients.Before joining the YDMPR program, Kevin completed a Ph.D. in physics at Johns Hopkins University and a post-doctoral certificate in Medical Physics at Virginia Commonwealth University. As a resident, he worked on clinical research projects involving diagnostic display quality control, CT dosimetry, patient shielding, and patient-specific technique charts in mobile and pediatric radiography. Several of these projects were presented as posters and a presentation at meetings of the American Association of Physicists in Medicine and the Radiological Society of North America. He is particularly interested in CT, MRI, and fluoroscopy, protocol management and optimization, and applying physics and mathematics to address practical problems. In addition to clinical duties, he enjoys and is active in resident education, and brings his recent experience as a resident to his position as Assistant Program Director for first-year residents in the YDMPR program.Dr. Grizzard is board certified in Diagnostic Medical Physics by the American Board of Radiology.
  • Education
    MSc, Oregon Health & Science University, 2020
    Roberto successfully completed the Medical Physics residency program in June 2022.Roberto graduated from Oregon Health and Science University with a Master of Science in Medical Physics. He is particularly interested in nuclear medicine clinical work and research. His thesis work consisted in the implementation of an image and dosimetry tool for I-131 MIBG therapy. He also hopes to learn more about AI and machine learning in medical physics.
