Research Interests

The research in my laboratory involves the investigation of ion channel pharmacology and biophysics.  Voltage-dependent sodium channels, which are responsible for generating action potentials in muscle (cardiac and skeletal muscle) and neurons, are susceptible to block or modification by numerous naturally occurring neurotoxins and synthetic agents.  My research has focused on the modification of sodium channel kinetics by Site 2 neurotoxins such as aconitine, lappaconitine, and batrachotoxin, as well as the block of sodium channels by a variety of local anesthetics and aminoglycosides.
