Ronald E. Gangnon, PhD

  • Professor
  • Department of Population Health Sciences
  • Department of Biostatistics and Medical Informatics
  • Department of Statistics (Affiliate)


Ronald Gangnon is Professor of Biostatistics with a joint appointment in the Department of Population Health Sciences and the Department of Biostatistics & Medical Informatics. He also has an affiliate appointment in the Department of Statistics. Dr Gangnon earned his BA degree in Mathematics and Economics at the University of Minnesota-Duluth (1992) and his MS (Statistics, 1994) and PhD (Statistics with emphasis in Biostatistics, 1998) from the University of Wisconsin-Madison. Dr Gangnon's research interests are in the development and application of statistical methods in clinical and epidemiologic research. Areas of methodologic interest include spatial epidemiology, with emphasis on detection and modeling of spatial and spatio-temporal clusters, syndromic surveillance, age-period-cohort modeling, multi-state models and ranking. Dr Gangnon serves as Director of the Biostatistics Core for the Childhood Origins of ASThma (COAST) project, a prospective birth cohort study of early childhood risk factors for the development of asthma and allergy. Dr. Gangnon also serves as senior statistician for the Beaver Dam Eye Study and the Wisconsin Epidemiologic Study of Diabetic Retinopathy. Dr Gangnon maintains active collaborative research programs in asthma and allergy, dysphagia, breast cancer, colorectal cancer, geriatrics, environmental epidemiology and osteoporosis.
