Assistant Professor, Department of Physiology and Biophysics, School of Biomedical Engineering


My lab focuses on feedback between cardiac mechanics and electrophysiology. The goals of my research program are to investigate mechano-sensitive mechanisms at the organ, tissue, cell, and subcellular levels; discover their relevance for heart rhythm in health and disease; and use this knowledge to develop novel targeted anti-arrhythmic therapies.

Our Group

We are exploring a variety of research topics within the fields of cardiovascular physiology and cardiovascular disease. My laboratory uses a range of innovative experimental approaches involving electrophysiology, mechanics, mechano-electric coupling, and device-based therapies to better understand cardiovascular pathologies such as cardiac arrhythmias and myocardial ischemia. People interested in learning and/or working with these techniques are most welcome to contact me.
