My research is focused on molecular imaging of cancer both to improve early and accurate diagnosis and to provide rapid assessment of tumor biology with physiological imaging, and on radiation therapy for cancer based on targeted molecular receptors within or on the cancer cell. I hope, with my collaborators, to use new tools to identify the risk level of an tumor at time of diagnosis, thus allowing up-front treatment decisions that will provide superior, safer and more cost-effective treatment strategies for each patient. I also work to discover new insights into tumor biology that will bring new opportunities for treatment, such as with peptide-receptor radiotherapy (PRRT). Importantly, I always consider if my research can lead to improvements in medical care that can ultimately be deployed with affordable, preferably off-the-shelf technology, in community hospitals throughout the US so that everyone can ultimately and quickly benefit from the contributions I am able to make to the care of patients suffering from cancer.
