Medical Physicist
Khalid Noori,
M.Sc.,
Khalid Noori, M.Sc., is a medical physicist at United Hospital Center, where he has contributed to quality assurance optimization, electron beam commissioning, and clinical credentialing. Since joining in 2023, he has played a key role in implementing QA processes in MOSAIQ and conducting shielding surveys for new vaults. He has experience with Pinnacle, Monaco, and RayStation treatment planning systems.
Khalid earned his M.Sc. in Medical Physics from Toronto Metropolitan University in 2022 and his B.E.Sc. in Process Engineering from Western University in 2020. His undergraduate research focused on Tetrazolium-based gel dosimeters, while his graduate studies explored liposome nanocarrier transition temperatures using T1-relaxation techniques. His expertise includes synthesizing nanocarriers, encapsulating contrast agents, and characterizing them through DLS, DSC, and cryo-TEM imaging.
Driven by a passion for medical physics innovation, Khalid continues to advance clinical and research initiatives to enhance patient care and radiotherapy practices.
Medical Physicist
Jimmy Stringer, Ph.D., DABR,
Dr. Jimmy Stringer, Ph.D., DABR, is a board-certified medical physicist with over 20 years of experience spanning clinical practice, medical device innovation, and leadership in the military, academia, and private sector. He currently serves as a Clinical Diagnostic Medical Physicist at the University of Cincinnati Health System.
Dr. Stringer earned his Ph.D. in Radiological Engineering from the University of Cincinnati in 2024, following an M.S. in Medical Physics from the University of Cincinnati School of Medicine and a B.S. in Physics from Xavier University. He began his career as a commissioned officer in the United States Air Force, serving as a Bioenvironmental Engineer and Medical Physicist, later becoming the Chief Industrial Hygienist for the Ohio Air National Guard. His military tenure included establishing a career pipeline for medical physicists and a deployment to Afghanistan.
Dr. Stringer later joined the Ann Arbor Veterans Hospital as a Therapy Medical Physicist, advancing to Chief of Medical Physics and serving on the National Therapy Physics Standards Review Board. His research focuses on optimizing proton radiotherapy dose delivery and exploring variations in radiation therapy dosimetry based on sex, disease state, and race. A recognized contributor to the field, he has published peer-reviewed papers, secured a patent, and spoken at national and international conferences. His work has been supported by grants from organizations including the National Institute for Occupational Safety and Health and the Nuclear Regulatory Commission.
