Research Interests:

My background is in human color vision. At the Medical College of Wisconsin, I worked with Drs. Jay and Maureen Neitz. I used behavioral and electrophysiological techniques to investigate the in vivo spectral sensitivity functions of different observers. Our results demonstrated that there is much interindividual variability in the relative number of L and M cones in the human retina. My work in Rochester will partially continue in this field, as I will employ the techniques of adaptive optics and retinal densitometry to determine the arrangement of the three cone types in the living human retina. An extension of this work will be to examine cone mosaics from subjects with color vision defects, as well as carriers of color vision defects. Other scientific interests include comparative color vision and the evolution and utility of trichromatic color vision.
