Dr. Swann (Ph.D. Zoology, University of Tennessee, 1998) specializes in cell and tissue biology. Her graduate work in inhalation toxicology investigated the use of cultured amphibian palatine ciliated epithelium as an effective model of mammalian tracheal epithelium. Current research with students in Senior Study centers on work with the ciliated protist, Tetrahymena pyriformis. By fluorescently labeling the actin cytoskeleton, students are able to investigate the cellular physiology of phagocytosis. She is also working with students to develop a novel approach to estimating population size of T. pyriformis cultures using a multimode spectrophotometer.
