 Abstract:  Natural Computing is an interdisciplinary research field that investigates human-designed computing inspired by nature as well as computation taking place in nature, i.e., it investigates models, computational techniques, and computational technologies inspired by nature as well as it investigates phenomena/processes taking place in nature in terms of information processing.
We are now witnessing exciting interactions between Informatics and the Natural Sciences. While the Natural Sciences are rapidly absorbing notions, techniques, and methodologies intrinsic to information processing, Informatics is adapting and extending its traditional notion of computation, and computational techniques, to account for computation taking place in nature around us. Natural Computing is an important catalyst for this two-way interaction.
One of research areas of Natural Computing is a computational understanding of the functioning of the living cell. We view this functioning in terms of formal processes resulting from interactions between (a huge number of) individual reactions. These interactions are driven by two mechanisms, facilitation and inhibition: reactions may (through their products) facilitate or inhibit each other.
In our lectures we present a formal framework for the investigation of these interactions. We motivate this framework by explicitly stating a number of assumptions that hold for processes resulting from these interactions, and we point out that these assumptions are very different from the ones underlying traditional models of computation. We discuss some basic properties of these processes, and demonstrate how to capture and analyse, in our formal framework, some notions related to cell biology and biochemistry.
The main (first) lecture gives an overview of this research area while the following lectures discuss specific research topics which are motivated by biological considerations as well as by the need to understand the underlying computations. The models we discuss turned out to be novel and attractive from the theory of computation point of view - this is extensively discussed throughout the lectures.
The lectures are of a tutorial style and self-contained. In particular, no prior knowledge of biochemistry or cell biology is required.
The presented framework was developed jointly with A. Ehrenfeucht from University of Colorado at Boulder.

 G. Rozenberg is a Professor of Computer Science at Leiden University, The Netherlands, and an Adjunct 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). He has published more than 500 papers, 6 books, and is a (co-) editor of about 100 books.
His current research interests are: natural computing, including molecular computing, computation in living cells, self-assembly, and theory of biochemical reactions, 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.
He is an editor-in-chief of a number of journals and book series. He is a member of an editorial board of about 20 journals and book series. He edited four handbooks in the areas of theoretical computer science and natural computing, most recently "Handbook of Natural Computing" published  by Springer Verlag (4 volumes, altogether over 2000 pages).
He was the President or the Steering Committee Chairman of a number of renowned organizations and conferences in the areas of computer science, natural computing, and nanoscience (among others, the President of the European Association for Theoretical Computer Science; the President of the International Society for Nanoscale Science, Computation and Engineering; the Chairman of the Steering Committee for DNA Computing Conference; and the Chairman of the Steering Committee for the International Conference on Theory and Applications of Petri Nets). He has been a member of the program committees and invited speaker for practically all major conferences in theoretical computer science and natural computing in Europe.
 He is a Foreign Member of the Finnish Academy of Sciences and Letters, a member of Academia Europaea, and he received Honorary Doctorates from the University of Turku, Finland, the Technical University of Berlin, Germany, and the University of Bologna, Italy. He has received the Distinguished Achievements Award of the European Association for Theoretical Computer Science "in recognition of his outstanding scientific contributions to theoretical computer science". He is a Highly Cited Researcher by ISI.
