Susan L. Edwards, PhD, is professor of biology and chairperson at Appalachian State University, Boone, NC. She received her PhD in comparative physiology from Deakin University in 2000. Her research program focuses on the identification and localization of ion transport mechanisms associated with osmotic balance, acid/base homeostasis, and more recently nitrogenous waste excretion in fishes. She is an active member of the American Fisheries Society and is currently the president-elect of its physiology section. She is also a member of the Canadian Society of Zoology, the Society for Experimental Biology, the Australian and New Zealand Society of Comparative Physiology and Biochemistry, and is a life member of the Mount Desert Island Biological Laboratory. She serves on the editorial board of Comparative Biochemistry and Physiology and has served on a number of panels for the National Science Foundation.
