Profile

My current research interests are framed around two general themes. First, how are ion channels modified in their function by changes in the cellular environment? Specifically, we are investigating how various lipids, derived from the cellular membrane, or naturally occurring steroid hormones, alter the function of voltage-gated ion channels. The ion channels do not work the same way all the time-- their function is dependent upon various endogenous modulators. We aim to understand how and why this interaction occurs, as well as the physiological significance of the changes in ion channel function. The changes impact nerve cell communication and processes such as learning and memory as well as the function of brain and heart in certain disease states. Second, we are interested in how ion channels in different life forms relate to one another, both structurally and physiologically. How did cellular excitability evolve and what adaptations in ion channel structure and function were required to support electrical activity of cells and eventually allow the development of a nervous system? By studying ion channels cloned from the genome of basal metazoans, we can better understand the evolutionary changes that have occurred in ion channel structure and function.
