This issue is my last as editor in chief of AI Magazine. It was a tremendous honor and privilege for me to lead AI Magazine, which I have done since 1999. It was a special pleasure to work with an outstanding team of volunteers—-the editorial board, column editors, and others—-and with the authors and reviewers, as well as with Mike Hamilton, managing editor, and the AAAI staff. As my administrative duties have expanded at Indiana University, where I am now executive associate dean of the School of Informatics and Com- puting, the time has come for me to pass the torch.
