Dr. Marcia Martinez received her Ph.D. degree from the Graduate School of the City University of New York, NYC. Her training included specializations in molecular, cellular and developmental biology as well as in genetics and immunology. Her current research centers on the contributory role of failures in central tolerance in the thymus and the development of autoimmune disease states such as systemic lupus erythematosus (SLE). SLE predominantly affects women of all races however, higher morbidity and mortality is observed among women of African American descent. Dr. Martinez’s group focuses on understanding the relationship between specialized groups of thymic epithelial cells called nurse cells and their interaction with developing T cells. Dr. Martinez also serves as the Chair of the Tuskegee University Institutional Animal Care and Use Committee, the Deputy Director for Research and Training for the Tuskegee University Health Disparities Research Institute and as the Program Director for the Tuskegee University MARC U STAR Honors Fellowship program.
