Fangyu Peng, M.D., is an Associate Professor of Radiology at UT Southwestern Medical Center and a member of its Nuclear Medicine Division. He also holds a secondary appointment in the Advanced Imaging Research Center. His clinical interests include general nuclear medicine, PET imaging, and computed tomography (CT), with a particular interest in oncology and neurology. 

Dr. Peng earned his medical degree at Jiangxi Medical College in Nanchang, China. He then earned a master’s degree in molecular virology at Chinese Academy of Preventive Medicine's Institute of Virology in Beijing. He earned a doctoral degree in microbiology and immunology at the University of South Florida College of Medicine in Tampa. He then completed a research fellowship program in hematopathology at Ball Memorial Hospital in Muncie, Indiana, before completing his residency in pathology at Upstate Medical University in Syracuse, New York. Dr. Peng then completed a residency in nuclear medicine at the University of Connecticut Health Center in Farmington, and in anatomic pathology at Hartford Hospital. He completed his formal training with a fellowship program in nuclear medicine and molecular imaging at the National Institutes of Health in Bethesda, Maryland.

Before being recruited in 2008 to enhance the Nuclear Medicine Division's translational research, Dr. Peng served as an Assistant Professor of Radiology and Pediatrics at Wayne State University School of Medicine in Detroit.

At UT Southwestern, he troubleshoots and improves imaging protocols, and actively participates in educational endeavors, in addition to his regular clinical responsibilities.

Dr. Peng focuses his research on inherited and acquired copper metabolism disorders in Wilson’s disease, Alzheimer’s disease, and traumatic brain injury, and investigates molecular imaging and targeted radionuclide cancer therapy with copper radionuclides. His research has been published in more than 50 peer-reviewed publications. He also invented and received a patent for intracellular trapping of radionuclides by enzyme-mediated reduction.
