A person in your field you look up to…

The late Ronald Klein at the University of Wisconsin, Madison, USA, “the father of ophthalmic epidemiology” and the PI of the landmark Beaver Dam Eye Study and the Wisconsin Epidemiological Study of Diabetic Retinopathy (WESDR). He provided the foundation for our understanding of the major causes of vision loss, the prevalence and long-term incidence of all major eye diseases and the risk factors for AMD and diabetic retinopathy, which has led to the foundation of clinical guidelines of care. He was my mentor and taught me clarity in formulating hypotheses, focused research questions and precision in analysis and interpretation of results. He was a giant in academic ophthalmology.
