This document discusses using data-intensive science to build better models of human disease. It argues that advances in data generation, computing power, and open information systems now make it possible to comprehensively monitor disease and molecular traits in populations. This could allow evolving disease models in a shared compute space to develop better understanding of complex biological pathways and their relationship to diseases. The document outlines several initiatives, including the Clinical Trial Comparator Arm Partnership and Sage Bionetworks, that aim to facilitate open sharing of genomic and clinical trial data to generate more powerful models and accelerate progress against human diseases.
