Jeremías G. Galletti, M.D., Ph.D., is a physician–scientist whose work sits at the crossroads of ophthalmology, immunology, and neuroscience. He leads a research group at the Institute of Experimental Medicine within the National Academy of Medicine of Buenos Aires. Part of Argentina’s National Research Council (CONICET), his team explores how inflammation and nerve activity interact in the eye, and what these processes can tell us about the brain. Dr. Galletti trained as both a medical doctor and immunologist at the University of Buenos Aires, where he also completed his ophthalmology residency at the Hospital de Clínicas and then served as chief resident.
Early in his career, he became fascinated by how the immune system helps protect the eye’s surface, and how this delicate balance can go awry in diseases like dry eye. His curiosity led him from the clinic to the laboratory and eventually abroad, completing research fellowships at Baylor College of Medicine in Houston (USA) through the ARVO and Fulbright programs. These collaborations continue today.
His laboratory investigates the neuroimmune mechanisms that underlie corneal nerve damage. Among other findings, his group discovered that specific immune cells (Th1 CD4⁺ T cells) and the sensory receptor TRPV1 play key roles in driving corneal axon loss and neuroinflammation in dry eye disease. These results are helping to redefine how scientists think about the relationship between the eye and the nervous system and are fueling the idea that the cornea could serve as a “window to the brain.”
In addition to his basic research, Dr. Galletti has led clinical studies using advanced imaging and corneal biomechanics to improve the diagnosis of keratoconus and other corneal conditions. He serves as Associate Editor for The Ocular Surface and Oftalmología Clínica y Experimental, and has received multiple awards for his scientific contributions, including recognition from the Wellcome Trust (United Kingdom), the Fulbright Program (USA), and the International Ocular Surface Society.
At the heart of his work is a simple idea: by looking closely at the eye, we can learn much more about the body as a whole. Through this integrative approach, Dr. Galletti and his team aim to uncover new biomarkers of neurodegenerative disease and to bridge the gap between ophthalmology and neuroscience, thus turning the eye into a powerful tool for understanding brain health.
