Our research group is interested in understanding the molecular mechanisms that underlie the morphogenesis of epithelial and neuronal tissues. Currently, we focus on the spatial regulation of the cytoskeleton and its functions by a novel family of GTP-binding proteins termed septins. Owing to the abnormal expression of septins in cancer and neurodegenerative diseases, our research aims to provide new insights into the cell biology of disease.
Elias Spiliotis received his Bachelor of Science from Boston College and Doctor Philosophy from The Johns Hopkins University. Subsequently, he moved to Stanford University, where he held a post-doctoral fellowship from The Jane Coffin Childs Memorial Fund for Medical Research. In the lab of cell biologist James Nelson, he focused on the regulation of the cytoskeleton and its functions by a novel family of GTP-binding proteins termed septins. Elias joined the Biology Department in the fall of 2008. He is a member of the American Society for Cell Biology and the American Association for Cancer Research; a recipient of the 2009 Drexel Career Development Award and was featured as the “Scientist to Watch” in the December 2010 issue of The Scientist magazine. Elias Spiliotis holds a joint appointment in the Department of Neurobiology and Anatomy (Drexel University College of Medicine), and serves as the Director of the Biology Cell Imaging Center. In his spare time, Elias has djed radio shows, written music reviews, and performed and recorded with an independent post-punk band.
