Computational Biology is a thorough introduction to the strategies and tools that drive modern bioinformatics research. This book presents both fundamental concepts and practical techniques, emphasizing data workflows, statistical models and software platforms that enable reproducible analyses. Each chapter blends theoretical explanations with hands-on examples designed to support readers as they develop skills in sequence analysis, molecular modelling, network simulation and data integration. Whether applied to basic research questions or clinical investigations, the methods presented in this volume serve as a versatile toolkit for the analytical challenges encountered across life-science disciplines. This book is intended for graduate students, postdoctoral researchers and professionals in computational biology, bioinformatics and related fields. It will also benefit life scientists seeking to apply quantitative methods to experimental data, as well as data scientists interested in biological applications. Prior exposure to basic programming concepts and molecular-biology principles will help readers follow examples and implement workflows.
