Scientific Interests

Dr. Harley Kornblum's lab works on brain development, brain repair and brain cancer. His lab was among the first to identify stem cell-like cells in brain tumors and aided in the development of the methods that are widely used to study brain tumors. The laboratory is investigating glioma heterogeneity and novel mechanisms by which glioma cells propagate themselves and resist therapy. Additionally, the Kornblum lab studies normal neural stem cells and mechanisms of plasticity and repair in stroke, brain and spinal cord injury.
