This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. The overall objective is to develop and deploy novel, web accessible, cluster-enabled, grid- aware software and data resources that allow investigators in biomechanics, biophysics and cardiovascular physiology to perform numerical experiments that are: structurally integrated from sub-cellular to whole organ scales; functionally integrated across interacting biological processes; and that integrate experimental data from a variety of sources, scales and modalities. We will explore and advance the synthesis of these integrative analyses so that investigators can develop computational models that integrate theory with empirical data both functionally and structurally to investigate experimentally motivated biomedical hypotheses. To achieve these goals, we propose to interact closely with the visualization, grid computing and data integration core research activities of the resource. To focus these developments on scientifically important questions, we have developed collaborative projects with investigators who are applying experimental and computational approaches to understand the cellular and molecular mechanisms of physiological and pathophysiological processes that are dependent on the three-dimensional anatomy of the whole heart for their manifestations in vivo. The primary application of this core will continue to be computational models of cardiac electromechanical properties that integrate from single myocyte biophysics to whole heart physiology and are validated with experimental measurements in well characterized animal models. Whereas the data components of these multiscale models and their experimental validation are specific to the heart, the computational methods and software are more general. Therefore, the aims of the renewal and the targeted users of the new tools under development extend beyond the biophysics of the heart to other biomedical applications including soft tissue biomechanics, electrophysiology, systems biology, and diagnostic medical imaging.
