Everything on this website belongs to one or more intellectual projects with defined hypotheses, goals, methods, and accomplishments. This online book contains background information and links for all the exposure-related research projects. In each chapter of this book, we provide descriptions of the history, methods and results of each research project. Note: Project and the different materials associated with each project (document, software, data set, etc.) have their own convenient summary webpage in addition to the information given here.
