Neurophysiological computations and mechanisms that mediate human vision, particularly changes in vision across the life span and in diseases of the retina and optic nerve. Current studies use psychophysical and electrophysiological methods, together with high-resolution retinal imaging (adaptive optics and optical coherence tomography), to study both normal aging and age-related diseases leading to blindness.

Teaching Interests:
Visual psychophysics and neural foundations of visual perception, color and spatial vision, human development and aging.

Courses Taught:
NPB90b/NPB164/NPB 261A,B,C / Psych 290 / NSC 261A Vision Science
