ProfileIon channels are protein machines that control how electrical signals are generated and propagated in the body. The activity of ion channels is fundamental to many aspects of physiology and behavior including learning, memory, our perception of pain and taste, how the body moves and how the heart beats. Using electrophysiology, microscopy and spectroscopy I study the regulation of ion channels in living cells to understand how channels function under normal conditions and what goes wrong to cause disease.
