Dr. Raghunathan received his first degree in Biomedical Engineering from Visvesvaraya Technological University, India, and subsequently his M.Sc and Ph.D in Bioengineering from the University of Strathclyde in Glasgow, UK. He then completed a postdoctoral fellowship at the University of Bristol, UK investigating the safety of tribological wear released from orthopaedic implants. He then made his foray into vision science by completing a postdoctoral fellowship at the University of California Davis, jointly in Drs. Chris Murphy and Paul Russell’s laboratories, investigating the principles underlying the mechanobiology of the trabecular meshwork and cornea.
The primary goals of my research program are: (a) to understand the role that extracellular matrix play in ocular diseases, (b) to develop and utilize engineering tools in studying biomechanics and surface phenomena at the ocular surface interface, and (c) to use materials based strategies for development and delivery of therapeutics.
Rachel Redfern received her bachelor's degree in biology from Texas A&M University and then her OD/PhD from the University of Houston, College of Optometry. In 2006, Dr. Redfern received the Institutional Ruth Kirschstein National Research Post-doctorate Award and the ARVO/Alcon Early Career Clinician-Scientist Research Award. Dr. Redfern is a member of the Association for Research in Vision and Ophthalmology, the American Academy of Optometry and the Tear Film and Ocular Surface Society. She is also a past William C. Ezell Fellow.
Her laboratory is interested in ocular surface inflammation/infection, the impact of contact lenses (e.g. scleral gas permeable lenses) on normal and diseased eyes and the functional and anatomical changes that occurs in the meibomian glands with age and disease. They perform human subject, animal and in vitro studies. Dr. Redfern’s laboratory is NIH funded to examine the impact of toll-like receptors on the production of damaging cytokines and matrix metalloproteases and beneficial antimicrobial peptides on the ocular surface.
Dr. Richdale joined the University of Houston College of Optometry in 2017. She was previously an Associate Professor and founding director of the Clinical Vision Research Center, and established the Myopia Control Clinic at the State University of New York College of Optometry. Dr. Richdale teaches and conducts research primarily in cornea and contact lenses and her work has been supported by federal, private and industry grants. She currently serves as Co-Chair of the Contact Lens Assessment in Youth (CLAY) study group. Dr. Richdale received her OD, PhD, and Cornea and Contact Lens Advanced Practice Fellowship from The Ohio State University.

Eric Ritchey, OD, PhD, FAAO is a 2001 graduate of The Ohio State University College of Optometry. After graduation, Eric completed a 2-year Advanced Practice Fellowship in Cornea and Contact Lenses at Ohio State, where his research focused on overnight orthokeratology and extended wear contact lenses. Following fellowship, Eric served as a Clinical Assistant Professor at the University of Missouri-Saint Louis College of Optometry before beginning his PhD training at Ohio State. During his PhD training, Eric’s research in the laboratory of Dr. Andy Fischer focused on the mechanisms behind refractive error development. After completing the PhD, Eric joined Johnson and Johnson Vision Care as a Principal Research Optometrist in the Emerging Technologies Group, where he worked on contact lens technologies to control myopia progression. After 4 years in industry, Eric decided to return to academia and will teach Ophthalmic Optics to 2nd year optometry students. Eric’s clinical interests are in specialty contact lens fitting, anterior segment disease and ocular prosthetics. His research activities will focus on myopia development and contact lenses.
