Optical Imaging Laboratory develops novel biophotonic tomography for early-cancer detection and functional imaging, using non-ionizing electromagnetic and ultrasonic waves. Research directions include: Photo-acoustic tomography (PAT), Thermo-acoustic tomography (TAT), Ultrasound-modulated (acousto-) optical tomography (UOT), Mueller optical-coherence tomography (M-OCT), Oblique-incidence reflectometry (OIR) and spectroscopy, and Modeling light transport in tissues.
