Informatics faculty conduct cutting-edge research in a range of clinical disciplines including pediatrics, radiology, pathology and nursing practice. They also utilize devices, data and information to better serve the needs of the public, the nation and the world. This effort involves innovation at a number of levels: understanding information needs, designing information models, deploying systems, and evaluating their impacts.
