The Decision Systems Group (DSG) is a biomedical informatics research and development laboratory at Harvard Medical School and Brigham and Women's Hospital. Its overall focus is on development of algorithms, software environments, and computer-based tools that support the work of health care professionals (physicians, nurses, and other practitioners) and biomedical researchers. The DSG conducts research in computer-based decision support for patients and physicians, information retrieval, clinical information systems, image-based reasoning, bioinformatics, informatics for global health, and a variety of machine learning applications.
The DSG is a key participant in the Boston-area Informatics Research Training program. DSG faculty teach and supervise trainees in the Master's of Biomedical Informatics program at Harvard-MIT, as well as post-doctoral fellows (mostly MDs and PhDs in computer science or statistics).
