PROFESSIONAL PREPARATION
Virginia Polytechnic Institute and State University, Blacksburg, VA, Textiles, B.S., 1973
Virginia Polytechnic Institute and State University, Blacksburg, VA, Polymer Chemistry, Ph.D., 1981
RESEARCH ACTIVITIES
Dr. Riffle currently mentors a research group comprised of 9 Ph.D. students, 1 research scientist, and 2 undergraduates. Their focus is on the synthesis of functionalized homopolymers and block copolymers and their activity in metal complexation and nanoparticle formation; and in characterizing properties of nanoparticle dispersions in biological media. Emphasis over the past decade has included investigations of magnetic nanoparticles for biomedical applications.
