Laura Marcu uses an innovative simultaneous time- and wavelength-resolved fluorescence spectroscope to do fluorescence lifetime imaging microscopy (FLIM) to discover the earliest signs of arterial plaques and to delineate the margins of tumors. Her work was discussed in the July/August 2011 issue of bioPhotonics magazine, in an article called, “Optical Spectroscopy Gives a Sharp Gaze into Tissues.”
