Dr. Roger W. Li, OD, PhD [EMAIL]

 

Academic Career Path

  • Roger Li received a clinical degree in Optometry (1995) and a Ph.D. degree (1999) from the Hong Kong Polytechnic University. Upon receiving his Doctoral degree, he spent two years working at the Centre of Myopia Research at the same institute. Dr. Li was a clinical instructor teaching clinical optometry and supervising intern clinicians at the University Optometry Clinic from 1995-2000.

 

  • In 2001, Dr. Li moved to the University of Houston and University of California-Berkeley to pursue further Post-Doctoral research training, and conducted a series of pioneering perceptual learning amblyopia treatment studies. In 2008, he joined the University of Hong Kong as Research Assistant Professor, and returned to continue his research at the University of California-Berkeley in 2009. He was promoted to Full Research Specialist in 2015.

 

  • Dr. Li subspecializes in amblyopia treatment, binocular vision therapy and clinical visual electrophysiology. He has published more than 35 peer-reviewed research articles in many high impact scientific and medical journals and has frequently been selected as a reviewer for numerous international journals and extra-mural grant funding organizations. Currently, he serves on the Editorial Boards of four international journals.
