DEVELOPMENT OF THERANOSTIC AGENTS

My laboratory is at the interface of chemistry and biology and is focused on developing molecules for the visualization and treatment of disease. Using novel chemistry platforms, we have the ability to produce molecules with multiple labels and thus, multiple applications.  For example, the addition of radioactive and fluorescent labels onto tumor-seeking agents has allowed us to develop new approaches to specifically identify cancer by whole-body and intraoperative imaging, respectively.   This could potentially provide surgeons with real-time intraoperative images that will distinguish cancer from normal tissue, minimize removal of healthy tissues, and identify small tumors which would otherwise be missed by the naked eye.  In cases where cancer has spread and surgery is not possible, we use our chemistry platform to selectively deliver toxins to tumors and visualize their effects in vivo, enabling personalized treatment protocols.  Our fundamental expertise in chemistry, imaging, and drug characterization has allowed us to establish diverse collaborations to study the in vivo properties of novel disease-targeted molecules, evaluate the potential benefits of modulating biomarker trafficking in cancer cells, and assess the effectiveness of emerging cancer treatments. Common to each project is our focus on translation of discoveries and technologies into the clinic to improve human health.
