PhD, Colorado State University - 2009
Stephen received a Ph.D. in Cell and Molecular Biology from Colorado State University in 2009. While working in the Department of Environmental and Radiological Health Sciences, he was integral in developing a rapid mammalian mutation assay and investigated the roles of DNA repair mechanisms following exposure to ionizing radiation, chemicals and hypoxia. Shortly thereafter he joined the Division of Medical Oncology as a Postdoctoral Fellow in the Jimeno lab. He has significantly contributed to the generation of a direct patient xenograft model of head and neck cancer, using it to study the roles of cancer stems cells and the epithelial to mesenchymal transition in resistance to therapy and tumor recurrence. In his free time Stephen enjoys hiking and traveling around the Colorado Mountains with his family.
