Milind Tambe is Helen N. and Emmett H. Jones Professor of Engineering and Founding Co-Director of the Center for Artificial Intelligence in Society at the University of Southern California. He is a fellow of the Association for Advancement of Artificial Intelligence (AAAI) and Association for Computing Machinery (ACM), recipient of ACM/SIGAI Autonomous Agents Research Award, Christopher Columbus Fellowship Foundation Homeland security award, INFORMS Wagner prize in Operations Research and others. He has contributed several foundational papers in AI in areas of intelligent agents and computational game theory, which have received best paper awards at major AI conferences including AAMAS, IJCAI, IAAI. Eric Rice is Associate Professor and Founding Co-Director of the Center for Artificial Intelligence in Society at the University of Southern California. An expert in community-based research and social network science and theory, he has spent the past several years working to merge social work science and AI to create solutions for major social problems such as homelessness and HIV. Since 2002, he has worked closely with homeless youth providers in Los Angeles and many other communities across the country to develop novel solutions to support young people across the nation who do not have a home, with the goal of ending youth homelessness.

'Tambe and Rice have created a novel collaboration which brings together computer science and social work researchers to address seemingly intractable social challenges. The variety of problems described in the collection on which cross-disciplinary teams have already made progress makes evident the promise of this new type of collaboration. The final chapter's thoughtful consideration of the ethical issues such work raises is a model for taking ethics into account from the start of designing artificial intelligence systems.'
