The major research interest of Dr. Barra's laboratory is the role of autoantibodies in Rheumatoid Arthritis (RA) and its associated complications, in particular vascular disease. We aim to investigate the immune mechanisms contributing to the increased rate of cardiovascular disease in patients with RA. The research is translational involving mouse models of RA and atherosclerosis, biomaker studies as well as epidemiologic studies with participation in various cohort studies.
