Dr. Sandra G. Williams earned her M.D./Ph.D. from Washington University in St. Louis, where her Biochemistry thesis project focused on understanding the evolution and molecular basis of RNA-protein interactions in a family of proteins found in the spliceosome. More recently, she completed residency training in Internal Medicine at Yale New Haven Hospital. She comes to the rheumatology fellowship at NIH with an interest in exploring the intersection of RNA biology and biochemistry with inflammatory disease.
For Brian Dizon, M.D., Ph.D., his interest in immunology began during college at the University of Miami when he volunteered in a lab studying host-pathogen interactions using Yersinia as a model organism; he subsequently graduated with a major in microbiology/immunology. He then went to medical school through the Medical Scientist Training Program at the University of Alabama at Birmingham, and under the mentorship of Dr. John Kearney, studied the role of self-reactive carbohydrate-specific B cells and their secreted antibodies in the early stages of autoimmune diabetes in NOD mice. His interest in autoimmunity through all stages of life led him to complete a residency in internal medicine-pediatrics at the University of Rochester, and he now pursues a combined rheumatology fellowship at the NIH. As he continues his training, he hopes to further explore the multifaceted roles of B cells in autoimmune disease at the basic/translational level.

Marcela A. Ferrada, M.D., received her Doctor of Medicine degree from the Universidad del Valle in Cali, Colombia, in 2004. Shortly after graduation, she moved to the United States to pursue an academic career. She worked at the University of San Diego as a post-doctoral fellow for two years. For her clinical training, she went on to Internal Medicine Residency at the University of Miami/Jackson Memorial Hospital where she also spent a year as a Chief Resident. She then pursued dual fellowships in Critical Care at the National Institutes of Health and Infectious Diseases at Johns Hopkins Hospital. During her fellowships, she completed all the required courses for a Masters in Health Science from Duke University. Upon completion of her clinical fellowships, she stayed on as a Staff Clinician in Critical Care at the NIH. However, Dr. Ferrada was diagnosed with Relapsing Polychondritis in 2015 and decided to make the study of this disease her life’s work. She is currently a clinical fellow in the Rheumatology Fellowship training branch at the NIH. Dr. Ferrada was the federal liaison for the relapsing polychondritis foundation until December 2017. She has given more than ten Grand Rounds in various hospitals in the United States about Relapsing Polychondritis, and is currently working with Peter C. Grayson, M.D., James Katz, M.D., Robert Colbert M.D., Keith Sikora M.D. and other investigators to study the disease.
