BiographyGuido Schäfer is the group leader of the Networks and Optimization Group (N&O) at Centrum Wiskunde & Informatica (since 2016). He joined CWI as a senior researcher in 2009. Since February 2021, he is professor by special appointment of "Algorithms, Optimization and Game Theory" at the Institute for Logic, Language and Computation (ILLC) of the Faculty of Science of the University of Amsterdam (UvA). The chair was established on behalf of the Beta Plus Foundation. From 2010-2020, he was professor by special appointment of "Algorithmic Game Theory" at the Department of Econometrics and Operations Research of the School of Business and Economics of the Vrije Universiteit Amsterdam. Before coming to CWI, he pursued his PhD studies at the Max-Planck-Institute for Informatics in Saarbrücken, Germany, and obtained his PhD in 2004. After that he was a postdocoral researcher at the Sapienza University of Rome (2004-2005) and a junior professor at the Institute for Mathematics of the Technical University Berlin (2005-2008). He received his Habilitation from the Institute of Mathematics at the TU Berlin in 2009.
His core expertise is in the areas of combinatorial optimization and algorithmic game theory. A large part of his research is concerned with the development of efficient algorithms for optimization problems. Another part is about devising algorithmic means to reduce the inefficiency caused by selfish behavior in large distributed systems. His research is fundamental in nature but addresses several real-world aspects that are of practical relevance, such as lack of coordination, uncertainty of data and limitations of resources. Results of this research find their applications, for example, in logistics, transportation, traffic and network routing, scheduling and auctions.
