The Barber lab is pioneering a molecular understanding of how intracellular pH dynamics regulates cell behaviors by bridging protein electrostatics and cell biology. Her work is distinguished in revealing the design principles of endogenous pH sensitive proteins regulating actin filament dynamics, cell adhesion, migration and differentiation, dysplasia, and gene expression.
