    Collapse Overview 
    Collapse overview
    Steven Walston, PhD, is a retinal electrophysiologist and biomedical engineer specializing in the development and implementation of neural interface technologies. His research has focused on investigating electrical stimulation strategies to restore vision with retinal prostheses and on understanding neural effects of retinal degeneration. Additionally, his research has focused on the development of nanomaterial-based electrode technologies and their integration into flexible thin-film microelectrode arrays in efforts to further enhance the quality communication at the electrode-neural tissue interface.
