Dr. Bellanti is Director of the International Center for Interdisciplinary Studies of Immunology at Georgetown University Medical Center and Professor of Pediatrics and Microbiology-Immunology at Georgetown University School of Medicine, Washington, DC. Soon after arriving at Georgetown, he realized that his goal of generating new knowledge in immunology and translating it to clinical use would require adopting a multi-disciplinary approach to immunology that would involve a horizontal matrix including both basic and clinical investigators, allied health professionals, statisticians, and health educators and the public. Accordingly, in 1975 he established and became the Director of the International Center for Interdisciplinary Studies of Immunology at Georgetown University Medical Center and later Director of the Division of Allergy-Immunology, Department of Pediatrics and the Division of Virology and Immunology in the Department of Laboratory Medicine of Georgetown University Hospital, positions he currently holds as consultant. The location of ICISI in the nation's capital has enhanced its international perspective; students, physicians, and scientists from all over the world are invited to study there.
