Research

My research is focused on the cellular and physiological function of Degenerin/ENaC ion channels. I am currently involved in studies of structure-function and regulation of the epithelial Na+ channel (ENaC), known to be involved in epithelial ion transport, and studies of related acid-sensing ion channel 5 (ASIC5) in the regulation of neuronal activity in the brain. My primary effort to date has been study of Degenerin/ENaC channels in fly sensory neurons with a focus on understanding the cellular function of these channels and their contribution to the ionic basis of sensory transduction and pain. This combined with recent advances in ion channel recording in fly sensory neurons, as pioneered by me, allows sensory function to be probed in parallel at the protein, cellular and whole animal levels.

I also have initiated a new project to investigate why some critical anti-cancer drugs that are widely used in the clinic cause pain. These side effects of anticancer drugs are little understood and limit the effective use of these key drugs. My research in this area has provided key understanding of the fundamental mechanisms that underlie chemotherapy induced pain.
