BEYOND DATA ALONE. “Instead, we need to leverage the ideas and techniques of systems biology to understand the behavior of the system and its multitude of parts. Similarly, the challenges that genomics is now tackling by integratively analyzing ever higher-dimensional, multi-species systems will likely require the development of more sophisticated hierarchical models by the systems biology community to enable meaningful joint comparative analyses.”
