Current Research:

The development of novel tissue engineering strategies for peripheral nerve regeneration. More than 18 million extremity injuries occur in the United States each year, resulting in a substantial number of peripheral nerve injuries. Nerve defects are a common result of these types of injuries and present a significant challenge clinically. Current treatments for peripheral nerve defects are limited and rarely lead to full functional regeneration. My research is focused on the use of a unique biomaterial derived from human hair keratins as a tissue engineering scaffold for peripheral nerve regeneration. Specifically, we are investigating the ability of keratin scaffolds to enhance the regeneration process through a nerve guidance conduit. We are finding that human hair keratins have remarkable physical, chemical and biological properties with superior biocompatibility and growth factor activity. In addition, we have discovered that the insertion of keratin scaffolds into a nerve guidance conduit enhances nerve regeneration in vivo. The goal of my project is to investigate the mechanisms by which keratins are able to facilitate the nerve regeneration process and to use keratin based scaffolds to promote regeneration of large nerve defects.
