Dr. Hauser studies genetic susceptibility to multiple sclerosis. For more than 15 years, Dr. Hauser has led the Multiple Sclerosis Genetics Group, a consortium of investigators at multiple sites across the US. He collaborated on the formation of an international MS consortium and is now the leader of a large consortium project on the genetics of MS. His contributions include efforts to identify informative MS families for linkage studies, collaboration on linkage studies and linkage disequilibrium studies to map genes, and finally larger scale association studies, both candidate genes and genome-wide, to identify MS susceptibility loci.
