Research interests
My principal research interest is in how calcium cycling is controlled in excitable cells, including cardiac and skeletal muscle as we as neurons. My focus is on the mechanisms by which calcium release from intra-cellular stores (endo/sarcoplasmic reticulum, ER/SR) is controlled by the type 2 ryanodine receptor (RyR2). The aim of my research is to characterize how the activity of RyR2 is altered both physiologically and in disease. This is achieved using a broad spectrum of assays from molecular biology and single channel recordings, through to isolated cells and tissue and ultimately whole animal models and patients.
