A. Personal Statement
Dr. Drummond is an Associate Professor in the Department of Physiology and Director of the Confocal Core
Facility at the University of Mississippi Medical Center, which includes a Leica TCS SP2 Confocal
Microscope and Leica TCS SP5 Multiphoton Confocal Microscope. She has 20 years of expertise in
fluorescence imaging. She is internationally recognized for her pioneering research for the role of Epithelial
Na+ Channel/Acid Sensitive Ion Channel (ENaC/ASIC) protein family in vascular function. Dr. Drummond’s
laboratory was the first lab to establish the putative mechanosensitive ENaC/ASIC protein expression in
vascular smooth muscle cells and their role in migration, pressure-induced constriction and blood flow
autoregulation. Furthermore, her laboratory was the first to demonstrate the presence of degenerin
mediated proton-gated and mechanically gated ionic currents in vascular cells.
