Karen E. Stine, PhD, is a professor of Biology and former dean of the School of Sciences at Auburn University at Montgomery in Alabama, USA. She has also served as the director of the undergraduate toxicology program at Ashland University in Ohio. She earned her PhD in toxicology from the University of North Carolina at Chapel Hill. Dr. Stine is a member of the Society of Toxicology and the Society of Environmental Toxicology and Chemistry. At Clemson University, Dr. Stine co-developed and co-taught a Principles of Toxicology course that was open to both undergraduate and graduate students. Her research interests are in the area of mechanisms of toxicity and focus on the role of stress proteins in cellular function and dysfunction. Dr. Stine has also authored or co-authored several research publications in the field of toxicology. Thomas Miller Brown, PhD, is president of Genectar Com LLC in Whitefish, Montana, USA which conducts research in toxicology, genetics, and genomics, now focusing on pigment cell development in the common wood nymph butterfly as a melanoma model. He earned his PhD from Michigan State University. Formerly a professor, Dr. Brown taught Toxicology of Insecticides, Principles of Toxicology, and Insect Biotechnology. He also led the discovery of an actively transposing short interspersed nuclear element (Insect Science 16:219–226). He has published papers on the biochemical toxicology of organophosphorus compounds and on the mechanisms of insecticide resistance in insects. Dr. Brown has also conducted research at Nagoya University and Tsukuba Science City in Japan.
