Quantitative Methods for Precision Medicine : Pharmacogenomics in Action

Modern medicine is undergoing a paradigm shift from a "one-size-fits-all" strategy to a more precise patient-customized therapy and medication plan. While the success of precision medicine relies on the level of pharmacogenomic knowledge, dissecting the genetic mechanisms of drug response in a sufficient detail requires powerful computational tools. Quantitative Methods for Precision Medicine: Pharmacogenomics in Action presents the advanced statistical methods for mapping pharmacogenetic control by integrating pharmacokinetic and pharmacodynamic principles of drug-body interactions. Beyond traditional reductionist-based statistical genetic approaches, statistical formulization in this book synthesizes elements of multiple disciplines to infer, visualize, and track how pharmacogenes interact together as an intricate but well-coordinated system to mediate patient-specific drug response.

Features:

• Functional and systems mapping models to characterize the genetic architecture of multiple medication processes
• Statistical methods for analyzing informative missing data in pharmacogenetic association studies
• Functional graph theory of inferring genetic interaction networks from association data
• Leveraging the concept of epistasis to capture its bidirectional, signed and weighted properties
• Modeling gene-induced cell-cell crosstalk and its impact on drug response
• A graph model of drug-drug interactions in combination therapies
• Critical methodological issues to improve pharmacogenomic research as the cornerstone of precision medicine

This book is suitable for graduate students and researchers in the fields of biology, medicine, bioinformatics and drug design and delivery who are interested in statistical and computational modelling of biological processes and systems. It may also serve as a major reference for applied mathematicians, computer scientists, and statisticians who attempt to develop algorithmic tools for genetic mapping, systems pharmacogenomics and systems biology. It can be used as both a textbook and research reference. Professionals in pharmaceutical sectors who design drugs and clinical doctors who deliver drugs will also find it useful.

Rongling Wu develops a transdisciplinary approach for building up multilayer, multiscale and multifunctional bridges that link genotype to phenotype. Dr. Wu asks, answers, and disseminates biologically meaningful questions in the boundaries of statistics, genetics, ecology, and evolution. He invented a statistical method called functional mapping to reveal the genetic architecture of developmental trajectories and incorporated this approach into the context of eco-evo-devo research aimed to unveil the genetic and ecological mechanisms underpinning evolutionary novelties. More recently, Dr. Wu has integrated evolutionary game theory and predator-prey theory through naturally omnipresent allometric scaling law into graph theory to create a new theory – functional game-graph theory. This new theory can unravel the internal workings of complex systems at an unprecedented level of detail by charting and tracing the causal, signed, and weighted roadmap of relationships among high- or even ultrahigh-dimensional variables from any data domains. The second part of this book represents the application of this theory to pharmacogenomic research. Dr. Wu received his PhD in forest genetics at the University of Washington in 1995. He was appointed as Assistant Professor of Statistics at the University of Florida in 2000 and awarded the University Foundation Professorship in 2007. Since 2008, Dr. Wu has been Professor of Public Health Sciences and Statistics, promoted to Distinguished Professor in 2015, and served as Director of the Center of Statistical Genetics at The Pennsylvania State University. Dr. Wu is a Fellow of the American Statistical Association and a Fellow of American Association for the Advancement of Science.

Dr. Sang and Ms. Feng are collaborators of this book writing project under the leadership of Dr. Wu. Dr. Sang got his PhD degree at Beijing Forestry University in 2019 and is currently working as Lecturer of Medical Informatics at Nantong University Medical School, China. Ms. Feng is a PhD candidate in computational biology at Beijing Forestry University and going to graduate in 2023. The research interest of both Dr. Sang and Ms. Feng lies in the statistical modeling of computational biology and its applications to a broader area of agriculture, forestry, medicine, and beyond.
