Jeff Goldberg MD, PhD
Dr. Jeffrey Goldberg is Professor and Chair of Ophthalmology and Director of the Byers Eye Institute at Stanford University, and a member of the National Academy of Medicine. His clinical effort is focused on patients in need of medical or surgical intervention for glaucoma and other retinal and optic nerve diseases, as well as cataract. His research is directed at neuroprotection and regeneration of retinal ganglion cells and the optic nerve, a major unmet need in glaucoma and other optic neuropathies, and his laboratory is developing novel molecular, stem cell and nanotherapeutics approaches for eye repair.
Dr. Goldberg received his B.S. magna cum laude from Yale University, and his M.D. and Ph.D. from Stanford University where he made significant discoveries about the failure of optic nerve regeneration. He did his clinical training in ophthalmology and then in glaucoma at the Bascom Palmer Eye Institute, and was awarded a fellowship from the Heed Foundation. He was named the 2010 Scientist of the Year by the Hope For Vision foundation, and received the Cogan award from the Association for Research in Vision and Ophthalmology in 2012. He was elected in 2010 to the American Society of Clinical Investigation, an honorary society of physician scientists, and in 2021 to the American Ophthalmological Society. He directs an NIH-funded research laboratory and is one of the scientists funded by the National Eye Institute’s Audacious Goals Initiative. In addition, he has developed significant expertise with implementing FDA clinical trials for optic nerve neuroprotection and regeneration. His goal is to translate scientific discoveries to patient therapies.

David Sullivan PhD
Dr. Sullivan is a Ph.D. graduate of Dartmouth Medical School (Hanover, NH), and until recently, an Associate Professor in the Department of Ophthalmology at Harvard Medical School and a Senior Scientist at the Schepens Eye Research Institute (SERI; Boston, MA). During his 38 years at SERI and HMS, his research focused on the interrelationships between sex, sex steroids and dry eye disease, as well as on the role of lubricin on the ocular surface. His studies involved basic, clinical, epidemiological and translational aspects, and required the establishment of new and unique experimental approaches (e.g., lipid analytical, proteomic and molecular biological methods). His research has led to authorship on over 260 scientific articles and 15 patents, as well as to the development of potential therapies for aqueous-deficient and evaporative dry eye disease. He was awarded numerous research grants from the National Institutes of Health, and served as a preceptor for 34 postdoctoral fellows. He was awarded The Carel C. Koch Memorial Medal Award from the American Academy of Optometry and the Donald R. Korb Award for Excellence, the highest award for excellence by the American Optometric Association.
He is a founder, recent President, and Chairman of the Board of Directors of the Tear Film & Ocular Surface Society (TFOS), a non-profit organization, which was created to advance the research, literacy, and educational aspects of the scientific field of the tear film and ocular surface throughout the world. He organized 10 International Conferences, oversaw the awarding of more than 225 Young Investigator Awards, and organized the TFOS International Workshops on Dry Eye (“DEWS”), Meibomian Gland Dysfunction, Contact Lens Discomfort, DEWS II, and the TFOS Workshop, entitled “A Lifestyle Epidemic: Ocular Surface Disease.”
Through TFOS he has helped to promote increased international awareness of external eye diseases, enhance governmental funding for tear film and ocular surface research, stimulate the development of therapeutic drugs and diagnostic devices, and influence the design and conduct of clinical trials of novel treatments for ocular surface disorders. TFOS has a distribution to many hundreds of thousands of basic scientists, clinical researchers and industry representatives in more than 80 countries.

Carlos Belmonte MD, PhD
Dr. Carlos Belmonte served as professor and chairman in Medical Schools of the universities of Madrid, Valladolid (Spain) and visiting professor in Harvard, Utah, Max Plank Institute of Florida in (USA) and New South Wales (Australia). He pioneered the study of the cellular and molecular mechanisms for peripheral sensory transduction in the non-visual structures of the eye, showing that trigeminal neuron nerves innervating the cornea subserve the modalities of polymodal nociception, mechanoreception and thermal reception, and also have additional trophic roles related to epithelial healing and ocular inflammation. Belmonte’s group also reported the types of corneal nerve terminal ion channels that determine the selective specificity of the different nerve classes; they developed a novel aesthesiometer which allowed to confirm the existence of qualitatively different sensory modalities in the human eye surface and to determine the relative contribution to sensations of the different functional nerve fiber types. Belmonte’s team dentified the role of TRPV1 and piezo2 channels on ocular nociception, and the activation of TRPA1 channels by bacterial endotoxins. They also discovered that channel receptor TRPM8 of corneal cold thermoreceptors are the transducer of low temperatures and osmolarity, demonstrating that cold fiber activation is concerned in the regulation of basal lacrimal secretion, spontaneous blinking and in the symptoms of Dry Eye Disease (DED) in aging and in LASIK dry eye. Belmonte’s research has strong therapeutic implications of clinical value, and produced several patented inventions to diagnose and treat ocular pain.
Professor Belmonte has dedicated a significant effort to the advancement of medical education in Spain, ecognized with the National Research Award “Rey Jaime I”, the National Prize for Biology and Biomedicine “Severo Ochoa” and the National Award in Medicine “Gregorio Marañón”, all presented by the Kings of Spain, and to the promotion of neurosciences and eye research worldwide and internationally with the Nature 2017 Lifetime Award for Outstanding Mentorship of the journal Nature, the Luis Federico Leloir Award of the Government of Argentina, the EA Balazs Prize of the International Society of Eye Research,ALCON Award, EA Balazs Medal of the German Ophthalmological Society, the Eucornea Medal and the European Vision Award.ARVO Golden Fellow and Honoree of the ARVO Foundation (USA). Dr. He is a member of the Academia Europaea, the National Academy of Sciences of Spain and the Akademie der Wissenschaften und der Literatur of Mainz,Germany, and Doctor Honoris Causa by the Universities of Castilla la Mancha, Spain and University of Cordoba, Argentina.Professor Carlos Belmonte, MD, PhD
