Dr. Johnson’s research is focused on the nano-scaled transport properties (charge, energy, spin, etc.) of nanostructures and single molecules, including carbon nanotubes, graphene, DNA, synthetic proteins, and other biomolecules. They are particularly interested in the physical properties of hybrid nanostructures and their use in molecular sensing. Other research interests include the development of scanning probe techniques for electronic property measurement of nanomaterials and nanodevices.

The Promise of Nanotechnology
“The use of nanotechnology in consumer products and industrial applications is growing rapidly, with the products listed in the inventory showing just the tip of the iceberg. How consumers respond to these early products — in food, electronics, health care, clothing and cars — will be a litmus test for broader market acceptance of nanotechnologies in the future.”
