Ryan McNabb
Medical Instructor in the Department of Ophthalmology

Dr. McNabb is an engineer by training with a research focus on combining optical coherence tomography (OCT) and robots for use in the ophthalmology clinic. He recently joined the Department of Ophthalmology faculty after post-doctoral training and serving as a lead Research Scientist under Dr. Anthony Kuo at the Duke Eye Center.

He enjoys working closely with clinicians to combine technology and medicine. He is the principal investigator on an NIH R21 grant for “Assistive Robotically Aligning OCT and Laser Photocoagulation Therapy of the Retinal Periphery” in collaboration with Dr. Cynthia Toth. This grant will develop robotically aligned OCT to locate suspected retinal breaks in a patient’s peripheral retina before they can become vision threating detachments.

McNabb earned his B.S. from North Carolina State University in Electrical Engineering and completed his doctoral training at Duke University in the Department of Biomedical Engineering under the mentorship of Prof. Joseph Izatt.
