Research Focus

Cardiomyocyte cell biology and molecular mechanisms of heart failure progression. We focus on cardiac membrane organization and function, with particular interests on T-tubule microdomain function and regulation.

Research Contributions

Defined molecular mechanisms and function of BIN1-induced membrane structures and subdomains within cardiac T-tubules.

Current investigations include:

Human and mouse model of heart failure. BIN1 and cytoskeleton-based mechanisms of T-tubule microdomains in intracellular calcium signaling, and mechanisms of T-tubule microdomain turnover and remodeling during heart failure.
