Biosketch

Research in my laboratory is focused on understanding the mechanisms of cardiovascular development and promoting adult heart regeneration. Cardiac myogenesis is one of key developmental events to build up the functional pumping unit (myocardium). Not surprisingly, this is a joint effort from many cell types in the developing heart including cardiac endothelial cells and epicardial cells besides cardiomyocytes. This also requires well-coordinated signaling communications among these cells. Unlike others, we are taking innovative approaches to determine whether and how epigenetic factors such as histone modifications in nonmyocyte compartments instruct myogenesis. These novel epigenetic regulation mechanisms may be harnessed to promote adult heart regeneration.

Indeed, promotion of heart regeneration is still posing a hard challenge to us, since the adult heart is one of the least regenerative organs in mammals. We hypothesize that restoration of the cell cycle activity along with resetting cardiomyocyte differentiation state through epigenetic manipulation may enable adult cardiomyocytes to regain regenerative capacity. We are actively testing this hypothesis in vitro (primary cardiomyocyte culture) and in vivo (genetic mouse models) employing multiple sets of cutting-edge technologies such as CRSPR-Cas9, proteomics, ChIP Seq and single cell RNA Seq. This line of studies may open up new avenues for promoting adult heart regeneration.

Our lab is currently well funded by both NIH and AHA. If you are passionate in doing basic and/or translation research in the field of cardiovascular development and regeneration, feel free to contact me. Talent and self-motivated students, postdocs, and visiting scholars are always welcome!
