Dan Arking is an associate professor at the McKusick-Nathans Institute of Genetic Medicine and Department of Medicine, Division of Cardiology at Johns Hopkins University.

The Arking laboratory studies the genomics of complex human disease, including autism and cardiovascular disease, with the primary goal of identifying and characterizing genetics variants that modify disease risk. The laboratory is currently developing improved genome-wide association study (GWAS) methodology, as well as exploring the integration of additional genome-level data (i.e., RNA expression, DNA methylation, protein expression) to improve the power to identify specific genetic influences of disease.
