Dee Unglaub Silverthorn studied biology as an undergraduate at Tulane University and went on to earn a Ph.D. in marine science at the University of South Carolina. Her research interest is epithelial transport, and work in her laboratory currently focuses on transport properties of the chick allantoic membrane. She began her teaching career in the Physiology Department at the Medical University of South Carolina but over the years has taught a wide range of students, from medical and college students to those still preparing for higher education. At the University of Texas she lectures in physiology, coordinates student laboratories in physiology, and instructs graduate students in a course on developing teaching skills in the life sciences. She has substantial experience with active learning in the classroom and has given workshops on this subject at regional, national, and international conferences. Dee is currently editor-in-chief of Advances in Physiology Education and past-chair of the Teaching Section of the American Physiological Society. She works with members of the International Union of Physiological Sciences to improve physiology education in developing countries. She is also a member of the Human Anatomy and Physiology Society, the Society for Comparative and Integrative Biology, the Association for Biology Laboratory Education, and the Society for College Science Teaching. Her free time is spent creating multimedia fiber art and enjoying the Texas hill country with her husband, Andy, and their three dogs.
