role of glycosaminoglycans in ocular surface development and pathology

Vivien J. Coulson-Thomas,Ph.D.

Associate Professor

My research involves primarily the study of glycosaminoglycans and proteoglycans in the fields of cornea, cancer, wound healing, stem cells, inflammation, development, spinal cord injury and nerve regeneration. This unique interdisciplinary approach aims to decipher the role of glycosaminoglycans in development and pathology. One of our ongoing projects is to unveil the role of hyaluronan (HA) in ocular surface development and pathology using knockout approaches. We have previously shown that umbilical cord mesenchymal stem cells synthesize a rich extracellular HA modified glycocalyx that regulates inflammatory cells enabling these cells to survive xenograft rejection. We are currently developing umbilical cord mesenchymal stem cells and their hyaluronan rich glycocalyx for treating inflammatory disorders.

Vallabh Das,Ph.D.

John and Rebecca Moores Professor
Department Chair, Vision Science

I received my undergraduate degree from the Birla Institute of Technology and Science, Pilani, India in 1992 majoring in Electronics Engineering. I then moved to the United States for graduate studies and completed a M.S and Ph.D. degree in 1998 in Biomedical Engineering from Case Western Reserve University, Cleveland, Ohio. My work, carried out under the mentorship of Dr. John Leigh, primarily examined the interactions between visual-oculomotor and vestibular systems. I did post-doctoral work at the Yerkes National Primate Research Center, Emory University with Dr. Michael Mustari from 1999 to 2002. During this time I learnt the technique of single cell extracellular recording in the awake-behaving monkey and also became interested in examining visual-oculomotor mechanisms in the strabismic primate. I was appointed to the faculty at Emory University in 2002 and received an independent investigator award from the National Institutes of Health in 2004 to study neural circuits mediating binocular coordination of eye movements in the strabismic monkey. I have since maintained continued NIH funding. I joined the faculty of the College of Optometry, University of Houston in 2009. The goal of research in my laboratory is to continue to uncover the disruption of neural processing in various brain areas in the strabismic monkeys. A better understanding of neural mechanisms that are affected in the different forms of strabismus will help develop rationally based therapy.

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.
