The Children's Hospital Informatics Program is one of several Boston area research and development groups in medical informatics that together offer the Boston-area Biomedical Informatics Research Training program is a consortium of leading informatics laboratories at Harvard, MIT, Boston University, and Tufts and is supported by a grant from the National Library of Medicine. The training program participants comprise a vibrant academic community of individuals with diverse backgrounds and broad-ranging interests, providing fellows with many opportunities for interaction and collaboration. For United States citizens and permanent residents, fellowships provide stipend, tuition, and travel funds, and are typically for two to three year periods. Trainees are primarily associated with a particular research group, depending on interests. In addition, the program provides many opportunities for educational, research, and collegial/social interaction among the faculty, students, and fellows of the training sites through the Harvard Medical School Center for Biomedical Informatics (CBMI). A wide variety of course offerings at Harvard, MIT, Tufts, and Boston University, seminars, journal clubs, and other forums for exchange of information provide all trainees with opportunities to learn about the variety of research being conducted at the various laboratories and in the affiliated institutions, as well as in the larger field of biomedical informatics.
