Research interests are focused on understanding the biology, physiology, and pharmacology of cardiac contractility and function in both normal and diseased hearts. Specifically, our translational research projects include (1) investigating guided differentiation of reprogrammed progenitor cells to form mature cardiac conduction cells for cardiac repair, (2) defining β-adrenergic receptor-mediated "biased" signaling, and (3) characterizing A-kinase Anchoring Protein (AKAP) "signalosomes" in β-adrenergic receptor signaling. By addressing clinically significant basic science questions, our overall objective in the McConnell Laboratory is to better understand cardiac signaling mechanisms and towards developing therapeutics for heart repair.
