Molecular imaging, defined as the in vivo characterization of biological processes at the cellular and molecular level, is an attempt to image the molecular makeup of the macrofeatures currently visualized using "classical" diagnostic imaging techniques. Classically, detection of malignant tumor cells in a background of normal or hyperplastic benign tissue is often based on differences in physical properties between tissues, which are frequently minimal, resulting in low contrast resolution.
Our laboratory concentrates on research related to the development and application of Molecular Imaging technologies, with specific focus on designing novel tools to image individual and multiple molecular markers of disease thereby increasing the sensitivity and specificity of medical imaging. We are also developing new uses of molecular imaging to define tumor margins during surgery and as theranostic tools to identify cancer for conventional surgical removal followed by PDT ablation of tissue not amenable to surgery.
