Jeffrey Guild, Ph.D., is Associate Professor of Radiology at UT Southwestern Medical Center and a member of its Medical Physics section. He provides clinical diagnostic medical physics services to Parkland Health and Hospital System, Children’s Medical Center, and Clements University Hospital and Clinics.

Dr. Guild holds a bachelor’s degree in physics from Harvey Mudd College in Claremont, California. He earned a master’s degree and doctoral degree in applied and engineering physics from Cornell University in Ithaca, New York. He then received advanced training in biomedical engineering through a fellowship at the Georgia Institute of Technology in Atlanta.

Prior to joining the faculty in 2006, he served as the Medical Physics Quality Control Manager for the Department of Radiology.

In his current role, Dr. Guild is the lead physicist responsible for diagnostic medical physics support for Parkland Health and Hospital System. These services include evaluating the performance of imaging equipment for regulatory and quality assurance purposes, specifying new imaging equipment and developing bid requests, designing and inspecting shielding in X-ray imaging rooms, providing physics oversight for American College of Radiology accreditation programs for computed tomography (CT) and ultrasound imaging machines, and performing patient specific radiation dose and risk estimates.

In addition to offering his clinical services, Dr. Guild provides lectures, conferences, and exam reviews in radiological physics to resident physicians. He also has collaborated on several clinically relevant research projects, such as studies in vascular surgery, resulting in various publications in peer-reviewed journals.

Dr. Guild currently serves on various committees, including CT Operations, Radiology User Group, the UT Southwestern Institutional Review Board, and he chairs the Radiation Protocol Committee for Interventional Fluoroscopy. He has professional affiliations with the American Association of Physicists in Medicine, where he is a member of the Alliance for Quality Computed Tomography. He also is a Diplomate of the American Board of Radiology, with certification in Diagnostic Medical Physics.
