Brian Dizon, M.D., Ph.D.
Brian Dizon received his B.S. in Microbiology/Immunology and B.A. in Chemistry at the University of Miami in 2003. With a strong interest in immunology, he continued his M.D. and Ph.D. training at the University of Alabama at Birmingham. Under the mentorship of Dr. John Kearney, he explored the functions of autoreactive carbohydrate-specific B cells in a mouse model of autoimmune diabetes. With his continued interest in regulating autoreactive B cells in human autoimmune diseases, Dr. Dizon completed an internal medicine pediatrics residency at the University of Rochester, followed by a combined adult and pediatric rheumatology fellowship at Children’s National Hospital and the NIAMS. In 2019, he joined Dr. Pierce’s lab as a fellow to study the signaling and regulatory mechanisms in autoreactive B cells, which may impact systemic autoimmune diseases such as lupus. In 2021, Dr. Dizon completed his rheumatology training and continued in Dr. Pierce’s lab as a NIAMS Metzger Scholar to further his research and clinical training. In the lab, he examines the signaling mechanisms of autoreactive B cells, such as atypical B cells, to understand their functions and regulation in chronic inflammation (such as malaria and systemic autoimmune disease), as well as vaccinations that elicit long-lasting humoral immunity.
Sandra Williams, M.D., Ph.D.
Sandra Williams received her undergraduate degree from the University of Chicago and her M.D. and Ph.D. from Washington University in St. Louis. She completed her residency in internal medicine at Yale New Haven Hospital and her rheumatology fellowship at the NIH. Dr. Williams was subsequently promoted to Metzger Scholar in Translational Research at the NIAMS. Her research studies the intersection of RNA quality control and autoimmune diseases such as systemic lupus erythematosus (SLE).
