Stochastic Approaches for Systems Biology This textbook focuses on stochastic analysis in systems biology containing both the theory and application. While the authors provide a review of probability and random variables subsequent notions of biochemical reaction systems and the relevant concepts of probability theory are introduced side by side. This leads to an intuitive and easy to follow presentation of stochastic framework for modeling subcellular biochemical systems. In particular the authors make an effort to show how the notion of propensity the chemical master equation and the stochastic simulation algorithm arise as consequences of the Markov property. The text contains many illustrations examples and exercises to illustrate the ideas and methods that are introduced. Matlab code is also provided where appropriate. Additionally the cell cycle is introduced as a more complex case study. Senior undergraduate and graduate students in mathematics and physics as well as researchers working in the area of systems biology bioinformatics and related areas will find this text useful. Olaf Wolkenhauer received his first degrees in control engineering from the University of Applied Sciences in Hamburg Germany and the University of Portsmouth in the U.K. He obtained his PhD from the University of Manchester Institute of Science Technology (UMIST) for research on the application of possibility theory to data analysis. Following a research lectureship at the Control Systems Centre at UMIST and a research fellowship at the Technical University Delft in the Netherlands he directed his research towards systems biology. This led to a joint senior lectureship with the Dept. of Biomolecular Sciences and the Dept. of Electrical Engineering and Electronics at UMIST. In 2003 he moved to the University of Rostock in Germany where he heads the Department of Systems Biology and Bioinformatics. He is a fellow of the Stellenbosch Institute for Advanced Study (STIAS). Olaf Wolkenhauers research interests are in mathematical modelling and data analysis. His work concentrates on a systems theoretic approach to understand the regulation control and coordination of complex dynamical systems.

He completed his MSc. in Advanced Control and Systems Engineering from the Department of Electrical Engineering and Electronics at the University of Manchester Institute of Science and Technology (UMIST) Manchester U.K. in 2002. In 2003 he moved to the University of Rostock in Germany as a research assistant in the Department of Systems Biology and Bioinformatics in the Institute of Computer Science. In 2009 he completed his PhD from the same department. He is currently working as a post doctoral research associate in the same department. His research focuses on stochastic modelling of biological systems. Webpage: www.sbi.uni rostock.de
