In February 2011, Dr. Cairo relocated to the New York Medical College where he is the chief of Pediatric Hematology, Oncology and Stem Cell Transplantation; director of the Childhood and Adolescent Cancer and Blood Disease Center; medical and scientific director of the Cellular and Tissue Engineering Laboratory; and professor of pediatrics, medicine, pathology, microbiology and immunology; and cell biology and anatomy. Dr. Cairo has over 300 peer-reviewed publications and over 850 national and international presentations. He is an international leader in childhood lymphomas and leukemias, stem cell transplantation, developmental therapeutics, experimental hematopoiesis and immunology, and stem cell biology and regenerative therapy. He is a pioneer in the use of cord blood stem cells for treating pediatric malignant and non-malignant diseases and the use of cord blood stem cells for potential regenerative therapy.
