How are visual acuity and daily activities affected by visual impairment? Previous studies have shown that vision is altered and impaired in the presence of a scotoma, but the extent to which patient-specific factors affect vision and quality of life is not well understood.

PhD Candidate
Psychological & Brain Sciences
University of California, Santa Barbara
Byron is a PhD student in the Department of Psychological & Brain Sciences. He was born and raised in St. Louis, Missouri. He moved to New York City to study psychology, where he received a BA in Psychology from St. John’s University (2015) and then a MA in Behavioral Neuroscience from Queens College (2017). Byron worked as a Research Operations Manager at a start-up company that develops assistive products for blind and low vision individuals (2017 - 2020).
Byron’s main research interest is studying how image processing and psychophysics can be used to understand how low vision conditions affect visual tasks. Specifically, how combining computational models with simulated low vision impairment conditions can help inform and enhance individualized vision capabilities.
Byron is supervised by Dr. Michael Beyeler in the Bionic Vision Lab and Dr. Miguel Eckstein in the Vision and Image Understanding Lab.

Predicting Visual Outcomes for Visual Prostheses
What do visual prosthesis users see, and why? Clinical studies have shown that the vision provided by current devices differs substantially from normal sight.
Publications
Furthering visual accessibility with extended reality (XR): a systematic review
We present a systematic literature review of 216 publications from 109 different venues assessing the potential of XR technology to serve as not just a visual accessibility aid but also as a tool to study perception and behavior in people with low vision and blind people whose vision was restored with a neuroprosthesis.
