The focus of my research is the study of functional gap junction mediated cell-to-cell communication in cardiac tissue under normal and pathophysiologic conditions. One area of particular interest is the elucidation of the role of cell-to-cell communication on donor cell engraftment, trans-differentiation and function as applied to cell transplantation therapies.
This research includes both an in situ model of a heterogeneous cardiac myocyte/stem cell co-culture and in-vivo small animal heart model. Confocal fluorescence microscopy, a multisite fiber optic imaging system and micro-electrode array data acquisition system are used to image and provide high temporal and spatial measurements of intracellular ionic and transmembrane voltage changes and electrical signal propagation in cardiac tissue.
