Boi Faltings

Boi Volkert Faltings (born April 10, 1960) is a Swiss professor of artificial intelligence at École Polytechnique Fédérale de Lausanne.

Education
Faltings was born in Gelsenkirchen, Germany, and he received a diploma with distinction from ETH Zurich in 1983, where he studied electrical engineering with James Massey. He obtained a Ph.D. degree from the University of Illinois at Urbana–Champaign in 1987 under the supervision of Ken Forbus. His thesis was entitled "Qualitative kinematics in mechanisms" and showed for the first time how to derive kinematic interactions from object shapes.

Work
Faltings is noted for work in artificial intelligence, especially in qualitative reasoning about mechanisms, case-based reasoning in design, constraint satisfaction in design and logistics, and intelligent user interfaces. His recent work has centered on multi-agent systems, in particular the DPOP family of algorithms for distributed constraint optimization, the blocking island abstraction technique for network routing, and game-theoretic techniques for eliciting truthful information, in particular the peer truth serum.

In 1997, Faltings co-founded the company Iconomic Systems, known for development of  an agent-based paradigm for travel e-commerce. He subsequently co-founded 5 other companies. Among them, in 2004 he co-founded NexThink, providing network security and data analytics. In 2007, he co-founded Prediggo, a company that provides recommender systems.

Faltings was nominated professor at the Ecole Polytechnique Fédérale de Lausanne in 1987 and promoted to full professor in 1993. He founded the Artificial Intelligence Laboratory and served as head for the Department of Computer Science. He has spent 6 months each as visiting professor at Stanford University and the Hong Kong University of Science and Technology. He has served as associate editor for numerous journals, including the Journal of Artificial Intelligence Research, the Artificial Intelligence, the ACM Transactions on Intelligent Systems and Technology, the ACM Transactions on Economics and Computation, and the ACM Transactions on Social Computing. He was president of the Swiss Group for Artificial Intelligence and Cognitive Science from 1995 to 2014, and member of the executive council of the Association for Advancement of Artificial Intelligence from 2014 to 2017.

Honors
In 1983, Faltings received the silver medal of the ETH Zurich for his diploma thesis. In 1984, he received an IBM graduate fellowship. In 2000, he received a distinguished service award from IFIP. In 2002, he was elected a Fellow of the European Coordinating Committee for Artificial Intelligence, and in  2012, he was elected a Fellow of the Association for the Advancement of Artificial Intelligence.
