Allison Hess-Dunning, PhD
Neural Interfaces, Microfabrication and Microdevices, Polymer-based biosensors, Novel substrate, electrode, and sensing materials for implantable microdevices.
Allison Hess-Dunning is a Research Investigator with the APT Center and the Louis Stokes Cleveland VA Medical Center. She received a B.S. in Engineering Physics from the University of Pittsburgh, and M.S. and Ph.D. degrees in Electrical Engineering from Case Western Reserve University. Dr. Hess-Dunning’s research interests center around developing multi-functional, locally-responsive neural probes for monitoring and improving brain activity and health through electrophysiology, electrochemical measurements, and drug delivery. Micro- and nano-fabrication processes are developed to integrate into the probes novel or unconventional materials, such as a mechanically-switchable polymer nanocomposite and graphene-based electrodes, to maximize biocompatibility and device viability.
