John  Hanfelt

Professor

Faculty, Biostatistics and Bioinformatics

My research interests include robust methods for sparse cluster-correlated studies, the theory of estimating functions and artificial likelihood,  and the application of high-dimensional latent class methods in Alzheimer's disease.  I direct the biostatistics/epidemiology program of the Georgia Clinical and Translational Science Alliance and co-direct the statistics/data management core of the Emory Alzheimer's Disease Research Center.  I am a Fellow of the American Statistical Association.
