Roman Słowiński is a Professor and Founding Head of the Laboratory of Intelligent Decision Support Systems within the Institute of Computing Science, Poznań University of Technology, Poland. Since 2002 he holds, moreover, professor’s position at the Systems Research Institute of the Polish Academy of Sciences in Warsaw.

He has done extensive research on methodology and techniques of decision support, including multiple criteria decisions analysis, preference modeling and knowledge-based decision support. This methodology employs a junction of operations research and computational intelligence. His particular interest is focused on: decision support, addressing robustness issues, soft and granular computing, ordinal data mining, preference learning, modeling of uncertainty and imprecision in decision problems; rough set theory; fuzzy set theory; multiobjective optimization; project scheduling, including multiple category resources, multiple job modes, multiple criteria and uncertainty; decision support in medicine, technology, economics and environmental studies.

As author or co-author, he has published 14 books and more than 400 articles, including 160 papers in major scientific journals. His ISI h-index=30. He supervised twenty four Ph.D. theses in Operations Research and Computer Science.

He has been professor on European Chair at the University of Paris Dauphine, and invited professor at the Swiss Federal Institute of Technology in Lausanne, the University of Catania, Polytech’Mons, University of Michigan-Ann Arbor, Yokohama National University, Université Laval-Québec, University of Missouri-Columbia, University of Osaka, Polytech’Tours, Ecole Centrale Paris.

He is laureate of the EURO Gold Medal (1991), and Doctor Honoris Causa of Polytechnic Faculty of Mons (2000), University Paris Dauphine (2001) and Technical University of Crete (2008). He holds, moreover, the Edgeworth-Pareto Award, by International Society on Multiple Criteria Decision Making (1997). In 2005, he received the Annual Prize of the Foundation for Polish Science, regarded as the most prestigious scientific award in Poland.

Since 1999, he is editor of the European Journal of Operational Research, and since 1990 he is, moreover, editor of Foundations of Computing and Decision Sciences. From 1998 to 2003, he was editor of Decision Analysis Section of the International Journal on Fuzzy Sets and Systems. He is on editorial board of eighteen other scientific journals. He organized the First International Workshop on Rough Set Theory and Applications in Poznań, in 1992. He is coordinator of the EURO Working Group on Multiple Criteria Decision Aiding and president of the International Rough Set Society. Moreover, he is „Senior Member” of IEEE and expert of the panel (PE6–Computer Science) in European Research Council.

Since 2004, he is member of the Polish Academy of Sciences, a corporation of 350 outstanding Polish scholars. He has been elected president of the Poznań Branch of the Polish Academy of Sciences for the term 2011-2014.
