Dr. McArdle is an epidemiologist with expertise in data science and data governance. He has extensive experience performing genetic analyses, including genome wide association studies.  He and his team have developed web based analytic tools to aid in the presentation and mining of results from large GWAS studies.  He has published on proper covariate selection in such studies, particularly when a change in phenotype is of interest, such as response to pharmaceutical treatment.  His experience includes a decade of involvement with the study of complex common disease in the Old Order Amish population.
