Dr. Shribak is a principal investigator of NIH RO1 grant on orientation-independent differential interference contrast and combined DIC-Pol microscopy. His current interests also include developing real-time polarized light microscopy for life cell imaging, 3-dimensional polarization microscopy, interferometric technique for measuring two-dimensional distributions of refractive indices based on a Jamin-Lebedeff microscope, correction of polarization aberrations in microscopes, and theory of polarization fluorescence.
