Through coursework and practica, Ph.D. candidates develop a strong foundation in information science, learning to identify critical problems and rigorously researching their solutions. Students become well versed in the scope, origins, methods, issues and theoretical framework that define the iSchool's uniquely interdisciplinary approach to the study of information. Ph.D. students at the iSchool come from a variety of professional experiences and academic backgrounds, such as information science, social sciences, computer science, library services, law, and information technology. Advances in data management, machine learning and artificial intelligence are reshaping the economy, science, politics and social life.
