The 2013 School of Information Theory is organized by Center for Science of Information ( http://www.soihub.org ), a National Science Foundation Science and Technology Center, and is sponsored by the IEEE Information Theory Society. Hosted at Purdue University from Tuesday, June 4 to Friday, June 7, 2013, the school provides a venue where doctoral and postdoctoral students can meet to learn from distinguished professors in information theory, and form friendships and collaborations. This year the school will introduce several interdisciplinary topics in the emerging field of science of information. Students will present their own research via a poster during the school. Although the focus is on information theory, interdisciplinary topics are welcome, e.g., topics related to mathematics, physics, biology, control, networking, etc.
