Dr. Shulman received his Bachelor of Science degree, his Doctor of Optometry Degree, and his Ph.D. degree from the University of Houston. After graduation from optometry school in 1981, Dr. Shulman practiced optometry in Houston in a private practice setting for ten years. He then returned to the University of Houston to obtain his Ph.D. degree in Physiological Optics and Vision Science. His primary area of research was retinal cell biology and his thesis concerned the effects of dopamine and lead on sodium - potassium ATPase in rat photoreceptors. After graduation in 1998, he spent several years in San Diego, California. Dr. Shulman then returned to the University of Houston, College of Optometry to teach the Ocular Anatomy laboratories and a portion of the Advanced Physiology course. In February 2005, he became the Assistant Dean for Student Affairs and Admissions. Dr. Shulman's favorite past-times are ice hockey (for which he is too old to play competitively now), baseball, and photography.
Retinal and neurophysiology, ocular morphology and cell biology, cell signaling and signal transduction including retinal dopamine involved in second messenger pathways.
Dr. Justin Simbulan graduated from the University of Houston College of Optometry (UHCO) with Magna Cum Laude in 2017. After graduation, he completed a residency in Primary Care at the Michael E. DeBakey Veterans Affairs Medical Center, where his training focused on ocular disease, specialty contact lenses, and low vision rehabilitation. After residency, Dr. Simbulan served as a full time staff optometrist at the Michael E. DeBakey Veterans Affairs Medical Center where he was involved with direct patient care and acted as an attending for optometry residents and intern students. In 2020, Dr. Simbulan joined UHCO as clinical faculty.
Dr. Simbulan enjoys a practice style that involves diagnosis and treatment of ocular disease such as glaucoma and macular degeneration, as well as participating in the overall management of patients with systemic conditions such as diabetes and hypertension to evaluate for ocular complications. He maintains strong interest in the fitting of specialty contact lenses such as scleral lenses and gas permeable contacts, and involvement in the management of low vision rehabilitation.
Professor Smith received his OD (1972) and PhD (1978) from the University of Houston and subsequently joined the faculty of the UH College of Optometry. During his tenure in the College of Optometry, he has served as the Chair of the Basic Sciences Department and as the Associate Dean for Graduate Studies and Research. Professor Smith currently holds the Greeman-Petty Professorship in Vision Development and is serving as the Dean of the College of Optometry.
Professor Smith’s research interests are focused on the optics of the eye. He received the Glenn Fry Award (1996) and the Prentice Medal (2010) from the American Academy of Optometry for his research on the role of vision in regulating refractive development and eye growth. Professor Smith has published over 150 referenced papers and received 29 years of research funding from the National Institute of Health's (NIH) National Eye Institute (NEI). He is also an accomplished lecturer, having received teaching awards at the department, college and university level and in 2003 was selected by the Texas Optometric Association as its Educator of the Year.
Professor Smith is an active member of the vision science community. He is a Fellow of the American Academy of Optometry, an ARVO Fellow (inaugural class), a past President of the American Optometric Foundation (2002), a past Member and Chair of NIH NEI's Central Visual Processing Study Section (1998-2003) and a past member of NIH's National Advisory Eye Council (2005-2008). Professor Smith currently serves on the Board of Directors of Prevent Blindness Texas, as the Secretary of the Partnership Foundation for Optometric Education, and as the Past-President of the Association of Schools and Colleges of Optometry.
Myopia, Visual Optics, Amblyopia, binocular vision, psychophysical and neurophysiological effects of abnormal visual experience.
Scott Stevenson received his PhD in Experimental Psychology from Brown University in 1987 for studies of visual suppression during eye blinks. He was an NRSA post-doc at UC Berkeley School of Optometry for three years, and then joined the research faculty there. Dr. Stevenson joined the faculty at UH in 1995.
Dr. Stevenson’s research concentrates on the visual control of eye movements, with emphasis on visually driven eye movement reflexes, such as for the control of eye alignment. Dr Stevenson is also active in the development of eye trackers based on high magnification retinal imaging in a broad collaboration involving researchers at a number of other institutions.
Dr. Stevenson teaches in courses on Vision Science, Perception, Optometry, Eye Movements, and Matlab for Vision Science.
Dr. Stevenson serves on the Editorial Board for Vision Research, and is a member of the Vision Sciences Society.
