The division, since its inception under the leadership of Dr. Stephen Hauser in 1992, has made major contributions all aspects of the understanding and treatment of MS including defining the full genetic risk profile for MS, discovering the importance of B cell biology in MS, improving our understanding of adaptive immune processes in inflammatory diseases of the brain and groundbreaking discoveries in the development of therapeutics for repair and remyelination in MS and other demyelinating diseases. The group continues to be dedicated to breakthrough developments in the field including microbiome research, glial biology work, and working to uncover the triggers of MS and other inflammatory diseases of the CNS. Under his leadership the group has expanded its focus to investigate new methods for understanding infectious and inflammatory diseases of the brain and developmental and autoimmune disorders of the CNS that lead to loss of regulation of normal glial cell biology.
