Biographical Sketch


Dr. Saatman received her undergraduate degree in engineering science and mechanics at the Virginia Polytechnic Institute and State University. She completed her Master's and Doctor of Philosophy in Bioengineering at the University of Pennsylvania. Her postdoctoral fellowship in neurotrauma research was performed at the University of Pennsylvania. Dr. Saatman's research activities focus on mechanisms of damage to the neuronal cytoskeleton, axonal injury, and calcium-mediated neuropathology in traumatic brain injury.
