Dr. Roger W. Li [EMAIL]

 

Academic Career Path

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

 

  • Dr. Li moved to the University of Houston College of Optometry in 2001 to pursue further Post-Doctoral research training in the area of spatial vision. He then joined the University of California-Berkeley School of Optometry in late 2001 as Research Associate, and later Associate Specialist conducted a series of perceptual learning amblyopia treatment studies.

 

  • In late 2008, Dr. Li joined the Department of Psychology at the University of Hong Kong as Research Assistant Professor of Visual Perception, where he taught the course Biological Neuroscience. Dr. Li returned to continue his research at the University of California-Berkeley School of Optometry in mid 2009.

 

  • Dr. Li specializes in amblyopia treatment and clinical visual electrophysiology. He has published numerous papers in many professional and scientific journals, and has frequently served as reviewer for many international journals and grant funding organizations. His research focuses on amblyopia treatment, clinical optometry, clinical vision science, visual electrophysiology, enhancement of visual functions, retina and brain imaging, myopic control, visual aging and telemedicine.
