Research Focus:  We are exploring the uses of a new imaging technology known as excitation-scanning hyperspectral imaging. Excitation scanning both reduces the acquisition time and increases the amount of signal available in fluorescence imaging studies. We're currently using this technology to expand the number of fluorescent signals available to a researcher in any given signal, as well as using the fluorescent molecules inherently found in the human body (called autofluorescence) to detect disease states. Specifically, I'm examining the use of excitation scanning hyperspectral imaging in colon cancer detection and atherosclerotic plaque detection in arteries.
