G. Rozenberg received his Master and Engineer degree in computer science in 1965 from the Technical University of Warsaw, Poland. In 1968 he obtained his Ph.D. in mathematics at the Polish Academy of Sciences, Warsaw. Since then he has held full time positions at the Polish Academy of Sciences, Warsaw, Poland (assistant professor), Utrecht University, The Netherlands (assistant professor), State University of New York at Buffalo, U.S.A. (associate professor), and University of Antwerp, Belgium (professor). Since 1979 he has been a professor at the Department of Computer Science of Leiden University and an adjoint professor at the Department of Computer Science of University of Colorado at Boulder, U.S.A. He is the head of the Theoretical Computer Science group at Leiden Institute of Advanced Computer Science (LIACS), and the scientific director of Leiden Center for Natural Computing (LCNC).

G. Rozenberg has published about 300 papers, 5 books, and is a (co-)editor of about 40 books.

He is the editor of the Bulletin of the EATCS, the editor of the series Advances in Petri Nets (Springer-Verlag), the managing editor of the Series on Natural Computing (Springer-Verlag), and a co-editor of the Monographs and Texts in Theoretical Computer Science (Springer-Verlag).

He has been a member of the program committees for practically all major conferences on theoretical computer science in Europe. G. Rozenberg is involved in a number of externally funded research projects on both national and international levels. His current research interests are: - DNA computing, - theory of concurrent systems, in particular theory of Petri nets, theory of transition systems, and theory of traces, - theory of graph transformations, - formal language and automata theory, - mathematical structures useful in computer science - in particular theory of 2-structures, - Computer Supported Cooperative Work.

He is a Foreign Member of the Finnish Academy of Sciences and Letters, a member of Academia Europaea, and a doctor honoris causa of the University of Turku, Finland.
