Expertise and Research Interests
My research interests can be broadly catergorized as the application of molecular imaging techniques such as positron emission tomography (PET) to the drug assessment process. My recent work has focused in on the measurement of cerebral blood flow in migraine headache, a disorder that effects 10% of the US population. My work centers on the measurement of cerebral blood flow (CBF) in migraine headache, as well as measurement of the response of CBF to migraine therapy as well as experimental models of migraine.
The characteristics of positron emitting radionuclides often make them ideal tracers for measuring drug effects. This includes the labelling of drugs with commonly used PET radionuclides such as C-11, or F-18. The ubiquitous nature of these nuclides allows for creation of labelled drugs nearly identical to their unlabelled counterparts. Through this technique I have been able to follow a commonly used inhaled steroid as it deposits in the airways, and explain the duration of action seen with this drug. A second area is the assessment of drug toxicity, using PET to measure drug effects on brain glucose utilization. PET has been used very effectively to measure brain glucose uptake as a means of supporting the diagnosis of numerous disorders including Parkinson's disease, Alzheimer's disease, and seizure disorders. These diseases produce characteristic reductions in brain metabolism. We are using this same technique to investigate drug effects on brain metabolism, particularly those drugs with either particularly severe toxicities (such as seizures) or which are used in patients who might be particularly susceptible to these toxicities.
