Preface

Cells are systems. Standard engineering and mathematics texts should provide an excellent intro-duction to understanding how cells behave, mapping inputs to outputs. Unfortunately, cells arenot linear, time-independent systems. Saturation and cooperative response break linearity. Cellularstates change with time. Cells are not even deterministic, violating the assumptions of non-linearsystems analysis.

This book provides a self-contained introduction to cells as non-linear, time-dependent, stochas-tic, spatial systems. Each major section is motivated by a canonical biological pathway or phe-nomenon that requires the introduction of new concepts. All the required mathematical techniquesare developed from the motivating examples.

The book is designed as a text for advanced undergraduate or graduate students. Prerequisitesare univariate calculus, linear algebra, basic molecular biology, and rudimentary facility with aprogramming language for computational experiments. Linear systems and Laplace transforms arehelpful, but are also reviewed in the initial chapters. Each chapter is designed to be covered in anhour lecture, and problems are provided in an Appendix.

This book is developed from course notes for “Systems Bioengineering III: Genes to Cells,”taught by me since 2007 as a required course for our B.S. in Biomedical Engineering.
