Research Interests:

Our laboratory uses sophisticated optical techniques to address fundamental questions in Alzheimer's disease research. Using the imaging technique multiphoton microscopy, the senile plaques of Alzheimer's disease can be detected in the brains of living transgenic mice, and characterized with chronic imaging. This allows direct observation of the natural history of this deleterious pathological event in the brain. In vivo imaging is also being used to characterize therapeutic approaches to clearing the senile plaques. Current research is aimed at optimizing anti-amyloid treatments, and imaging the anatomy and physiology of specific cell types in the brain before and after treatment. We have implemented a variety of structural and functional fluorescent readouts that can be imaged at a variety of time-scales in the living brain of the mouse models of neurodegeneration. Development of novel high resolution optical techniques is ongoing, and includes methods to measure and quantitatively analyze protein-protein interactions using fluorescence lifetime imaging microscopy (FLIM). We are also developing non-invasive approaches to amyloid imaging in intact animals that should ultimately translate to the clinic. This approach is truly multidisciplinary and involves active collaborations with chemists, physicists, and neurologists. While the goals of my research are related to answering specific questions about Alzheimer’s disease, the techniques are broadly applicable to other biological problems.
