Executive Director

Dr. Laura Walker is the founding Executive Director of the Envision Research Institute. She completed her Bachelor of Science in Chemical Engineering at the Massachusetts Institute of Technology and Doctorate of Philosophy in Vision Science at the University of California, Berkeley. At Berkeley, she studied with Dr. Jitendra Malik using psychophysics to validate computer vision algorithms. During her postdoctoral training with Drs. Preeti Verghese and James Coughlan at the Smith-Kettlewell Eye Research Institute in San Francisco, she developed a computational model of eye movements and as an Associate Scientist, continued to apply and develop that model to predict how changing eye movements can improve vision for different retinal diseases. Her most recent project at SKERI examined the impact of central vision loss on eye-hand coordination. Her ultimate goal at ERI is to take what is learned in the laboratory and translate it into rehabilitation therapies for individuals with low vision.
