Marcello André Barcinski is an MD (State University of Rio de Janeiro, 1965) and PhD (Federal University of Rio de Janeiro, 1974) with post-medical and post-doctoral training at, respectively, the Mount Sinai School of Medicine in New York, NY, and the National Institutes of Health in Bethesda, MD, US.
 Dr. Barcinski was still a medical student when he began his research training at the Institute of Biophysics (presently, Instituto de Biofísica Carlos Chagas Filho) at the Federal University of Rio de Janeiro, where, in 1988, he became Full Professor of Biophysics.
Taking advantage of the multidisciplinary approach to science prevailing at the Institute of Biophysics, he created the Laboratory of Immunogenetics which expanded its frontiers into several areas of immunological research and grew to what is now the Program of Immunology, producing high quality research and providing training for PhD. candidates in Immunology.

In 1991, he moved to the Department of Parasitology at the University of São Paulo, with the aim of developing research in Immunoparasitology. In 1999, he was appointed by the Brazilian Ministry of Health to assist in the reorganization and expansion of research at the National Cancer Institute, in Rio de Janeiro. There, he created the Division of Experimental Medicine, and organized the Graduate Program in Experimental Oncology.
 Dr. Barcinski is a member of both the Brazilian Academy of Science and the National Academy of Medicine. He acted as Vice-President of the Brazilian Federation of Experimental Biology Societies (FESBE), President of the Brazilian Society of Immunology (SBI), member of the Brazilian Commission of Biotechnology (CTNBio), among other positions in research administration.

He has served as permanent or ad hoc member in several national and international granting and policy-defining agencies such as the Brazilian National Research Council (CNPq), National Coordination for Higher Education (CAPES) and the World Health Organization (three years as member and another three years as President of the Tropical Disease Research Steering Committee on Chagas Disease).
 He also headed the Local Organizing Committee of the 13th International Congress of Immunology, held in Rio de Janeiro, Brazil, in 2007. As a retired Full Professor he is now a Visiting Researcher at the Oswaldo Cruz Institute in Rio de Janeiro. He is still publishing original and review papers in high-quality journals and mentoring graduate students in Immunology and Parasitology.
