Research summaryOur lab investigates how changes in cardiomyocyte organisation influence function in cardiac arrhythmia and heart failure.

Research

My lab is primarily interested in the ultrastructural organisation of cardiac muscle cells. Our focus is on how this changes in different types of heart disease and the impact it has on cardiac function. This includes studying the organisation of different structures and proteins involved in calcium handling in the heart, such as the transverse tubules and dyadic proteins. Our current project is looking at the role of a calcium-binding protein in the development of atrial fibrillation - the most common cardiac arrhythmia. We use a combination of techniques, including immunohistochemistry, western blotting, confocal microscopy of fixed and live samples, as well as super-resolution imaging.
