I am interested in molecular imaging in cancer and in infectious diseases. I am very interested in the imaging of metabolic pathways and of receptor imaging. I also stress the importance on impacting care to improve patient outcomes, and try to use technology that can be useful in larger community hospitals throughout the US.


I have several ongoing investigations on somatostatin receptor imaging in epithelial cancers correlating with genomics and proteomics and in early diagnosis of lung cancer.
