David R. Williams received his BS from Denison University in 1975, his PhD from the University of California, San Diego in 1979 under the mentorship of Donald I.A. MacLeod, and completed a postdoctoral fellowship at Bell Laboratories, Murray Hill in 1980 with John Krauskopf. He is currently William G. Allyn Professor of Medical Optics in the Institute of Optics at the University of Rochester. From 1991 to 2021, Williams directed Rochester’s Center for Visual Science, an interdisciplinary research program of over 40 faculty investigating the mechanisms of human vision. Awards include Optica’s Edgar G. Tillyer Award (1998), the Association for Research in Vision and Ophthalmology’s Friedenwald Award (2006), the Lighthouse Guild’s Bressler Prize (2007), the Champalimaud Vision Award (2012), election to the National Academy of Sciences (2014), the Arnold and Mabel Beckman Foundation’s Beckman-Argyros Award (2015), and Research to Prevent Blindness’ David F. Weeks Award (2020).
