Kenneth Louis Kramer, PhD

Chair, Department of Medical Education

Associate Professor

Kenneth L Kramer is an Associate Professor and Chair in the Department of Medical Education as well as the M1 Component Director. After receiving his Ph.D. from the University of Cincinnati in Anatomy and Cell Biology, he did postdoctoral work at the University of Utah and was an investigator at the National Heart, Lung, and Blood Institute. His main area of research is in developmental glycobiology, and he works with numerous undergraduates and several labs at Creighton in focusing on ear and brain development in zebrafish. Ken has a passion for medical education, seeking innovative approaches to teaching anatomy and histology. In addition to being active in the American Association of Anatomists for many years, he enjoys outreach programs to area budding scientists through BioEYES Omaha and the Nebraska Science Festival.

Research Focus

The vertebrate inner ear relies on specialized bundles of cilia on the apical surface of sensory hair cells to transduce sound and movement into electrical signals. The Kramer Lab uses the transparency of the early zebrafish embryo to visualize how ciliary linkages to extracellular structures regulate inner ear function. Using modern genetic and imaging tools, we collaborate with several labs across campus to determine how zebrafish mutants and drug treatments affect hearing and balance behaviors.
