Dr. Mefford completed his BS in Textile and Polymer Chemistry at Clemson University in 2003. He earned his PhD in Macromolecular Science and Engineering in 2007 from the Virginia Polytechnic Institute and State University and also received the Virginia Tech Graduate Man of the Year award. Before returning to Clemson University, Dr. Mefford worked on a variety of projects as a Researcher for the Ohio State University Department of Chemistry.
His research focuses on developing stable, biocompatible polymer-magnetite nanoparticle complexes and composites for biomedical applications. These applications include: developing materials for hyperthermia, investigating the thermal properties of macromolecule-nanoparticle complexes, and crosslinking networks of magnetic nanoparticles. The development of such complexes and composites will demonstrate the stability and interactivity of nanoparticles and improve upon them to give a better functionality for a given application.
