Dr. Pomper’s research projects in central nervous system imaging include using positron emission tomography (PET) and advanced magnetic resonance spectroscopy (MRS) techniques to uncover brain metabolic correlates of AIDS dementia; using PET to study molecular (neurotransmitter) and cellular abnormalities in patients with AIDS dementia; and the development of new radiopharmaceuticals for imaging nicotinic and glutamatergic neurotransmission as well as for imaging inflammation.
In oncology, he focuses on advanced magnetic resonance imaging (MRI) techniques, such as diffusion tensor and amide proton transfer imaging to study brain tumors. In addition, radiopharmaceutical and optical imaging agents are being developed to study prostate cancer, metastatic potential, infection, inflammation and to study the pharmacokinetics of chemotherapeutic agents in vivo. Molecular-genetic imaging of cancer is another priority.
His research group consists of chemists, physicists, molecular biologists and clinicians working together toward clinical molecular imaging.

The Johns Hopkins Small Animal Imaging Resource Program (SAIRP) works to generate the confidence necessary to move new cancer therapies to patients. Its ultimate goal is to move small animal imaging science forward to the point where the incorporation of such imaging techniques becomes second nature in the daily practice of cancer researchers.
