Biography

Dr. Eagar received his PhD in immunology and molecular pathogenesis from the Northwestern University Medical School in Chicago in 2001. He then completed an immunology fellowship at the University of California at San Francisco and an HLA fellowship at Houston Methodist Hospital. Dr. Eagar was an assistant professor in the Department of Pathology and Immunology at The University of Texas Southwestern Medical Center in Dallas before joining the Department of Pathology and Genomic Medicine here in 2013.

Description of Research

Dr. Eagar is board certified in histocompatibility by the American Board of Histocompatibility and Immunogenetics. His research interests include identifying immune processes involved in the pathogenesis of multiple sclerosis and transplant rejection, with a focus on finding novel regulatory pathways involved in T cell activation that might be harnessed for therapeutic intervention.
