Dr. Rafael Casellas was born in Buenos Aires and lived in Geneva, Paris, and Helsinki before coming to the United States where he received his Bachelor of Science in Chemistry from Brigham Young University in 1996. He received a Ph.D. in Molecular Immunology from the Rockefeller University in 2002. There, he worked under Dr. Michel Nussenzweig studying the role of immunoglobulin gene expression and recombination in the establishment of B cell tolerance and peripheral activation. From 2002 to 2003 he did postdoctoral training with Nobel Laureaute David Baltimore at the California Institute of Technology. There Dr. Casellas continued his molecular studies of B cell activation and developed new mouse gene targeting techniques. In January 2004, Dr. Casellas moved to the Molecular Immunology Branch of the NIAMS as a tenure-track investigator to form the Genomic Integrity and Immunity Group. Dr. Casellas is also serving as an adjunct investigator at the Center for Cancer Research, NCI.
