Injury to the corneal epithelium can occur through mechanical or chemical trauma, as well as through elective refractive surgeries (e.g., LASIK or PRK). Despite our current understanding that neutrophil recruitment to the injured cornea can be important for wound healing, many questions remain regarding the molecular mechanisms regulating neutrophil migration within the corneal stroma. Our research suggests neutrophil migration is influenced by molecular interactions with keratocyte (stromal cell) networks embedded between the stromal collagen lamellae. The hypothesis being evaluated is that PMN motility on keratocytes is regulated by inflammatory mediators (chemokines) and adhesion molecule-dependent interactions. Information gained from these studies will help delineate novel adhesive mechanisms underlying neutrophil migration in the injured cornea and this may define new targets for therapeutic treatment of ocular inflammation associated with injury or infection.

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.
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.
The focus of research in my laboratory is to investigate disruption of eye movement control in animal models for strabismus (ocular misalignment). Strabismus is a common visual developmental disorder affecting 2?5% of all human infants. Though the exact etiology of strabismus is still unknown, it is clear that disruption of binocular visual information in infancy plays a critical role in development of strabismus. Many seminal behavioral, anatomical and physiological studies have revealed various aspects of visual sensory deficits that are associated with the strabismic condition. By the same token, we know relatively little about disruptions in neural oculomotor (eye movement) circuits, though these structures must also be involved in maintaining the steady-state strabismus. The possible involvement of such structures ranges from altered eye muscle lengths to neural mechanisms that alter eye muscle tone or contractility. Our research is therefore directed towards identifying and understanding the roles of specific areas in the brain that may be involved in producing oculomotor properties describing the strabismus state. Our strategy is to utilize a basic science approach with studies in animal models, incorporating concepts, tools and techniques developed via basic science studies of the oculomotor system. To this end, we use a multi-pronged strategy involving behavioral studies of eye alignment, eye movements and ocular accommodation, MRI studies evaluating extraocular muscle (EOM) structure and single cell recording studies of information processing in neural oculomotor circuits.

The goal of our research lab is to better understand what happens in the eye in patients with diabetes. Diabetes is the leading cause of preventable vision loss in working aged Americans. It affects both blood vessels and nerves in the retina as well as the front of the eye. We evaluate retinal nerve function with a multifocal electroretinogram and nerve and vascular structural changes with an OCT and retinal photographs. We hope to understand the timeline of changes to structure and function as the disease progresses. We also hope to learn how gender, diet, and health differences play into vision loss in these patients.
