  • Research Summary:
    Ion channels are fundamental for the workings of the nervous system. We study the function, regulation, and evolution of voltage-dependent ion channels. Our main focus has been to study the regulation of sodium and potassium channels by hormones such as testosterone, estrogen, and by phosphorylation. A major emphasis of the laboratory has been cloning these ion channel genes and understanding their transcriptional regulation. In addition, we have been studying the molecular evolution of ion channel genes in vertebrates.
