Research Interests:

Dr. Gangnon collaborated with Dr. Matthew Davis on the development of severity scales for age-related macular degeneration using tree-structured models and for diabetic macular edema using model-based clustering techniques adapted from my dissertation research. He has served as senior biostatistician for the Beaver Dam Eye Study and the Wisconsin Epidemiologic Study of Diabetic Retinopathy. In a recent series of papers, he and his colleagues have advocated for the use of multistate models for incidence, progression and regression of age-related macular degeneration (AMD) as the preferred analytic approach. Using these models, they have demonstrated that the effect of the CFH Y402H risk allele is monotonic and detectable at all stages of AMD, that late AMD was associated with increases in overall mortality, and that misclassification of AMD explains most apparent regression of AMD, as well as demonstrating the impact of AMD severity in one eye on incidence and progression in its fellow eye.
