Geraldo Aleixo Passos received his PhD degree in biochemistry (1988) from Ribeirão Preto Medical School, University of São Paulo, USP, Brazil. His postdoctoral studies were conducted at the Molecular Genetics Institute of Montpellier (CNRS), France (1992-94) with sequencing and physical mapping of the human immunoglobulin lambda locus on chromosome 22q11.2. During several years he worked in close collaboration in the microarray laboratory at Centre d¿Immunologie de Marseille-Luminy (CIML, Marseille, France) (1999-2001) and then in the Unité INSERM 1090 in Marseille (2002-17) to study the large-scale gene expression in the thymus.  He is currently Associate Professor (Genetics and Molecular Biology) at School of Dentistry and Ribeirão Preto Medical School (USP, Campus of Ribeirão Preto, Brazil). He is the coordinator of the Molecular Immunogenetics Group. He was the adviser of two PhD theses awarded by Ministry of Education/CAPES: in 2008, one of his students received the CAPES Thesis Award and in 2010, another student received the distinction CAPES Thesis Honor in Genetics.
