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.

My research interests include environmental and behavioral influences on circadian rhythm and eye growth. Light exposure has a close link with numerous aspects of human physiology and has been implicated in several different pathological processes including myopia development, circadian rhythm disturbances, mood disorders, cancer, and metabolic disorders. The intrinsically photosensitive retinal ganglion cells (ipRGCs) are an inner retinal photoreceptor type that respond directly to short wavelength blue light, and are responsible for non-image forming functions including circadian rhythm entrainment and pupil size. Ongoing projects in the lab include 1) measuring and correlating light exposure with ipRGC activity, circadian rhythm patterns, melatonin levels and refractive error, 2) determining the effects of blue light emitting devices (computers and hand held electronic devices) on ipRGC function and sleep/wake patterns, and 3) developing devices to continuously and objectively measure behaviors related to eye growth.

Visual quality is limited by a host of factors, including imperfections (or aberrations) in the optics of the eye and the health of various cell types in the retina used to detect light and process this information for subsequent delivery to the brain. Using psychophysical, optical and functional imaging techniques, my primary goal is to better understand how the eye's optics and structure of the retina and optic nerve head affect vision in normal and diseased eyes. After completing my BS degree in Optics from the University of Rochester in 1997, I continued my graduate work in Optics at the University of Rochester's Institute of Optics under the advisement of David Williams. My graduate research focused on constructing a clinical wavefront sensor to measure the optical quality of a large population of normal and postoperative laser refractive surgery eyes, and on investigating the sources of aberrations induced in conventional and customized LASIK (laser in-situ keratomileusis) procedures. In collaboration with Ian Cox (Bausch & Lomb) and Scott MacRae (University of Rochester), I examined changes in the eye’s optical quality after cutting a corneal flap and after performing a laser ablation, how aberrations were induced due to static shifts of the pupil (such as changes in pupil center location with dilation), and characterized dynamic eye movements that occur during surgery. I also assisted in the design of the Rochester Adaptive Optics Ophthalmoscope, an instrument capable of both imaging individual photoreceptors and of conducting visual psychophysics in living human eyes.
Upon receiving my PhD in Optics in 2004, I conducted my postdoctoral work with David Williams at the Center for Visual Science (University of Rochester) in the area of high-resolution retinal imaging using adaptive optics. Adaptive optics is a relatively new technology that can measure and correct for the eye’s aberrations, leading to substantial improvements in image quality when a subject looks through an adaptive optics system. Conversely, the same instrument can provide an extremely sharp view of a subject’s retina with the capability of imaging individual cells in a living eye. As a postdoc, I contributed to the construction of a fluorescence adaptive optics scanning laser ophthalmoscope (AOSLO) that can noninvasively acquire in vivo reflectance and fluorescence images of individual photoreceptors, ganglion cells and retinal pigment epithelium cells. In September 2006, I joined the faculty at the University of Houston’s College of Optometry.
Our lab’s main goals are to learn more about the mechanisms responsible for the development and progression of retinal diseases (such as glaucoma and photoreceptor-based degenerations) and how the retina develops in the normal eye. To this end, we have built a dual deformable mirror, fluorescence AOSLO to image single cells in living eyes, thereby allowing us to conduct experiments that could only otherwise have been done in excised tissue. These experiments are often complimented with the use of other clinical and research-based imaging techniques (such as spectral domain optical coherence tomography) and visual function examinations (including perimetry, electroretinography, etc.) to investigate structure-function relationships. Several projects in the lab revolve around imaging retinal and optic nerve head structures in normal and glaucomatous eyes, as well as in eyes with color vision deficiencies and retinal disease. For example, through our currently funded NIH R01 grant , we seek to better understand the relation between in vivo changes in lamina cribrosa and optic nerve head geometry, axonal damage and vision loss in glaucoma. We also conduct engineering research, often to help facilitate our scientific goals, in areas such as optimal methods for controlling deformable mirrors and non-traditional methods of wavefront sensing and adaptive optics correction. Our AOSLO provides the opportunity to non-invasively monitor normal and diseased retinal structure and function on a cellular level in the same eyes over time. The ability to see cellular structures in vivo could enhance our ability to better diagnose retinal diseases and track the efficacy of potential treatments.
