I am a radiochemist working in Memorial Hospital’s Department of Radiology with a focus on the synthesis and development of positron-emission tomography (PET) imaging probes. I have a PhD degree in chemistry and while a post-doctoral fellow at Memorial Sloan Kettering, I developed an interest in biology. During my fellowship, I synthesized fluorine-18 and iodine-124 labeled molecules, which can act as PET probes for imaging HSV1-tk gene expression or function as a marker for proliferation, a hallmark of cancer. The information obtained from PET imaging was used to assess the biological status of the tumor cells. Since many disease states, including cancer, involve alterations in basic biological functions of the cells, information regarding these alterations can aid in diagnosis of disease and help in planning the most effective treatment. Non-invasive PET imaging is powerful technique which provides us with vital biological information which can be extremely useful in disease diagnosis and management. With this background, I became interested in development of PET/radiochemical probes which augment solving fundamental biological problems. Since this requires a multidisciplinary effort, I am extremely lucky and grateful to have colleagues who are experts in fields ranging from chemistry to radiology. We enjoy extremely fruitful collaborations and interact very closely on all aspects of research. My current research interests and collaborations include:
