Following his doctorate, he did a postdoctoral fellowship at the University of California, Berkeley studying the retinal basis of color perception using advanced high-resolution imaging.
Dr. Sabesan’s research group studies how the human retina enables the fundamental, yet, intricate aspects of our daily vision - color, motion and so on; and how such visual capacities are disrupted in the face of retinal diseases.
To achieve this, they develop and use novel imaging tools which enable them to see, stimulate, manipulate and record the functional activity of individual retinal cells in living humans.
Ultimately, they aim to use these high-resolution functional assays as biomarkers for early disease diagnosis and end-points for the treatment of blinding retinal disorders.
