Research Interests

Working in close collaboration with the radiochemistry laboratory of Dr. Victor Pike, my laboratory uses in vivo imaging to evaluate novel positron emission tomographic (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 neuroinflammation (including translocator protein, COX-1, and COX-2) and intracellular signal transduction (eg, cAMP phosphodiesterase). A major goal of the lab is to use these radioligands to facilitate clinical trials of novel therapeutics. Such trials are in the early planning stages with regard to phosphodiesterase-4 (PDE4) and neuroinflammation in depression.
