Dr. Peng has been developing new techniques for molecular imaging of inherited and acquired copper metabolism disorders in Wilson's disease, Alzheimer's disease, and traumatic brain injury. Dr. Peng is also studying copper metabolism as a imaging biomarker for molecular imaging and therapy of cancers, including prostate cancer and hepatocellular carcinoma. Additionally, Dr. Peng and his colleagues are developing new theranostic copper complexes for molecular imaging and targeted therapy of neuroblastoma, prostate cancer, and breast cancer. Education
