Research Interests:

My specific research focus lies in understanding the mechanisms underlying biomechanical stress responses in the heart, which play a central role in the pathophysiology of heart disease and arrhythmias. Little is known about how mechanical stress is sensed by cardiac cells, transduced into intracellular signals and how dysfunction of these pathways lead to heart disease and arrhythmias. Our research interests are in uncovering new pathway(s) mediating biomechanical stress responses in cardiac cell biology and disease, with a specific focus on sarcomeric and cardiac cell-cell junction proteins, which have specific importance in mechanical stress driven genetic based cardiomyopathies, such as dilated and arrhythmogenic right ventricular cardiomyopathy as well as cardiac arrhythmias. Our laboratory uses a multi-disciplinary approach, which combines molecular, cellular, developmental and physiological techniques as well as establishes genetic mouse and human stem cell model systems to provide a platform to translate, validate and test therapeutic approaches identified through our research.
