    My Scopus ID is 7005554863.

    Research Areas:
    Ionic channels, voltage gated ionic channels, fluorescence signal detection and electrophysiology, particularly as they relate to excitation-contraction coupling in striated muscle. Shannon uses multiple biochemical, biophysical and molecular approaches to study the control of the concentration of calcium in the storage organelle (the sarcoplasmic reticulum) of normal and abnormal cells of the heart.
