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. Greg G. Goss, PhD, is a professor in the Department of Biological Sciences at the University of Alberta, Canada, and is cross-appointed to the School of Public Health. He is also a Fellow of the National Institute of Nanotechnology. He earned his PhD at the University of Ottawa. He is the past winner of the Petro-Canada Young Innovator Award, the Canadian Society of Zoologists Early Investigator Award, the American Physiological Society Young Investigator Award, the McCalla award for teaching and research, and was awarded a Killam Annual Professorship in 2009–2010. Dr. Goss’ research focuses on toxicology and comparative physiology in a variety of fish species. He has served as president of the Canadian Society of Zoologists and serves on the councils of numerous national and international societies. He is an associate editor of the Canadian Journal of Zoology and is on the editorial boards for Nanotoxicology and Environmental Science: Nano.
