Research Topics

My laboratory develops and uses positron emission tomographic (PET) radioligands to study pathophysiology in several neuropsychiatric disorders. Working in close collaboration with the radiochemistry laboratory of Dr. Victor Pike, we use in vivo imaging to evaluate novel PET radioligands, first in animals, then in healthy human subjects, and finally in patients. My laboratory has multidisciplinary expertise in pharmacology, animal experimentation, clinical neuroscience, digital image analysis, and human evaluation of investigational radiopharmaceuticals. In addition to traditional receptor targets, we use radiolabeled probes for in vivo imaging of intracellular signal transduction (e.g., cAMP phosphodiesterase), gene expression (e.g., dopamine transporters expressed on transplanted embryonic stem cells), and a mitochondrial protein that is a marker for inflammatory cells (activated microglia and macrophages).
