Penelope Bouziotis is Research Director at the Institute of Nuclear & Radiological Sciences, Technology, Energy & Safety, currently Head of the Radiochemical Studies Laboratory, NCRS Demokritos. Her research is focused on the development of radiolabeled diagnostic and therapeutic agents for cancer. Dr. Bouziotis was the first researcher to introduce the Ge-68/Ga-68 generator in Greece, in an attempt to promote the development of novel radiotracers with positron-emitting isotopes. Recent research activity has been focused on 68Ga-labeled nanoparticles for dual-modality PET/MRI imaging of cancer, as well as on the development of radioimmunomagnetic nanoparticles for the simultaneous MRI imaging and beta-targeted therapy of cancer.
