Bosma Enterprises Postdoctoral Research Fellow

Dr. Arun Kumar Krishnan is a Bosma Enterprises Research Fellow with the Envision Research Institute, working under the mentorship of Dr. Susana Chung, a Vision Scientist at the University of California-Berkeley (an Affiliated Scientist with the Envision Research Institute). He earned a Bachelor of Science in Optometry from the Elite School of Optometry, India.  Under the guidance of Dr. Harold Bedell and a team of vision scientists, he earned his Doctorate of Philosophy in Physiological Optics and Vision Science from the University of Houston, College of Optometry.  Dr. Krishnan worked as a teaching assistant for the Geometric and Physical Optics, Perception and General Anatomy labs at the University of Houston, College of Optometry for 6 years, and in a hospital-based clinical optometric practice in various specialties including Pediatric Optometry, Binocular Vision–Orthoptics and Low Vision Care for 3 years. His doctoral research focused on understanding the relationship between the structural and functional losses at the preferred retinal locus (PRL) of subjects with bilateral central vision loss, such as macular degeneration, and also explored the impact of simulated vision loss on reading performance. He is currently studying macular lesions in patients with central field loss and exploring applications that improve reading performance for such patients. Dr. Krishnan’s research will deepen our understanding of how remaining vision can best be utilized and retrained to regain reading function. Dr. Krishnan is an active member of various scientific communities and regularly presents his research, including audiences such as the Association for Research in Vision and Ophthalmology (ARVO) and the American Academy of Optometry (AAO).
