Cherlyn J. Ng,Ph.D.

Sr. Research Scientist

Cherlyn Ng was born and raised in Singapore, where she went on to earn her BSc in neuroscience and PhD in x-ray crystallography from the National University of Singapore. Drawing upon her earlier experiences with audio/visual production, she received postdoctoral training in computational modeling, psychophysics and developed a deep interest in visual perception. Her current interests focuses on how the brain processes and represents sensory information, with particular emphasis on binocular vision. However, traditional psychophysics does not distinguish between percepts that arise from neural mechanisms and visual limitations that are caused by the imperfect optics of the eyes. She addresses this conundrum by coupling psychophysics with adaptive optics technology. This method minimizes optical limitations by correcting for the optical aberrations in the eyes so that percepts brought about by the neural mechanisms can be measured in isolation. These measurements serve the eventual purpose of building a unified model that explains how the brain chooses between selecting and balancing information from the two eyes.

Jason Porter,Ph.D., FAAO, FARVO

Associate Professor

Dr. Jason Porter is an Associate Professor in Physiological Optics and Vision Science and in Biomedical Engineering at the University of Houston. He earned his BS, MS, and PhD in Optics from the University of Rochester’s Institute of Optics. As a graduate student and postdoctoral fellow with David Williams, he worked in the areas of ocular aberration measurement, customized correction, and high-resolution retinal imaging using adaptive optics. During this time, he was lead editor for the book entitled, “Adaptive Optics for Vision Science,” a collaborative work that describes the principles and practices of adaptive optics in vision science.  

At the College of Optometry, Dr. Porter’s laboratory investigates mechanisms responsible for the development and progression of neuro-ophthalmic and retinal-related conditions (including glaucoma, traumatic brain injury / concussion, and inherited retinal degenerations). Recent work has also examined how foveal structure changes during normal development and in myopia. Dr. Porter’s laboratory has built an adaptive optics scanning laser ophthalmoscope to noninvasively image and monitor normal and diseased retinal structure on a cellular level in the same eyes over time. These experiments are often complimented with the use of clinical imaging techniques and visual function examinations to investigate structure-function relationships. The laboratory also conducts engineering research, often to facilitate its scientific goals, in areas such as optimizing methods of adaptive optics control and developing neural networks to automatically segment perfused retinal vasculature.
