MARTIN G. POMPER is Professor of Radiology, Director of the Small Animal Imaging Resource Program, and Associate Director of the In Vivo Cellular and Molecular Imaging Center, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA. He received his Ph.D. in organic chemistry and M.D. from the University of Illinois at Urbana-Champaign, Urbana, Illinois, USA. Dr. Pomper serves on the editorial boards of several publications and is currently Editor-in-Chief of Molecular Imaging. His research interests include the development of new probes and techniques for molecular imaging of cancer, focusing on radiopharmaceutical development and clinical translation. He is the immediate past president of the Molecular Imaging Center of Excellence of the SNM. JURI G. GELOVANI is Professor and Chairman, Department of Experimental Diagnostic Imaging and Director, Center for Advanced Biomedical Imaging Research (CABIR) at the University of Texas M.D. Anderson Cancer Center, Houston, Texas, USA. He received his M.D. and Ph.D. in clinical Neurosurgery & Neuroimaging from the University of Tartu, Tartu, Estonia. Prof. Gelovani is the pioneer of non-invasive molecular-genetic imaging using radiotracers. He is one of the co-founders of the field of modern molecular imaging. His research is dedicated to improving cancer detection and non-invasive molecular-genetic profiling, imaging-based selection of novel individualized anti-cancer therapies and monitoring their efficacy, including targeted small molecular and nanopartical based therapies, genetic and cellular therapies. He is leading the development of a premiere research program aimed at the discovery of novel and more specific chemical, genetic, and cellular tracers for imaging different tumor-specific targets, while continuing to mentor and teach graduate and postgraduate students. In 2008, Prof. Gelovani served as President of the Society for Molecular Imaging, which he had co-founded, and as the Organizer-in-Chief of the First Molecular Imaging Congress 2008.
