Caroline Haythornthwaite is a faculty member at the Graduate School of Library and Information Science, University of Illinois at Urbana-Champaign, where she is also Coordinator of the Undergraduate Minor in Information Technology Studies. Before returning to full-time study, she spent over 10 years in software development as a programmer, systems analyst, and software development manager. Her research focuses on how people work and learn together at a distance via computer technology and the Internet, and examines what combinations of computer media, and work and social communications build ties and social networks online. Current projects include examination of learning networks and community ties among distance learners, and processes of knowledge co-construction among members of distributed research teams.
