Professor Emilia Entcheva is recognized for pioneering cardiac optogenetics - the genetically mediated light sensitization of heart cells and tissue to allow optical stimulation, imaging and control of their electrical activity. The goal of Prof. Entcheva’s laboratory (the Cardiac Optogenetics & Optical Imaging Laboratory) is to work out the biophysical limits of and develop the technological innovations needed for a fundamentally new highly-parallel framework for all-optical cardiac electrophysiology in vitro and in vivo. Guided by her lab's theoretical/computational work in the area of bioelectricity, they experimentally integrate, test and validate new optical modalities for actuation (stimulation), including optogenetics, and sensing (fluorescent and dye-free optical mapping) of the electromechanical function in cardiac cells and tissues. Their tools are particularly useful for mechanistic dissection of cardiac cell excitation, cell-cell communication and spatiotemporal phenomena like cardiac arrhythmias, in response to pharmacological, genetic or other manipulations, in lab-on-a-chip platforms, using single primary or stem-cell-derived cardiomyocytes and engineered tissues, as well as in vivo animal models. This is done in a high-throughput fashion not affordable by other methods.

Her group leads efforts in the concept and development of new fully automated high-throughput all-optical electrophysiology platforms to improve drug testing, human stem cell research and gene therapies for the treatment of cardiac arrhythmias.  They collaborate with companies or other researchers to characterize the electromechanical function of disease-specific patient-derived iPS-CMs in a massively parallel fashion. In addition to contributions to the field of computational optogenetics (in collaboration with Dr. Trayanova and Boyle at JHU), they have recently demonstrated the first application of optogenetics for dynamic “wave control” by light in living tissue using patterned light (collaboration with Dr. Bub, Oxford). Their goal is to stimulate and engage others in the cardiac community in adopting these newly available all-optical tools for dissection and control of normal and abnormal heart function
