A.T. Charlie Johnson

Alan T. Charlie Johnson is an American physicist and a professor in physics and astronomy at the University of Pennsylvania. Johnson currently serves as the founding executive editor of the scientific journal AIP Advances and the co-founder of Graphene Frontiers, LLC.

Johnson's research is in experimental nanoscale physics, which combines nanotechnology and biophysics. His work specifically involves the transport within nanostructures and carbon nanotubes, which revolves around graphene, DNA, synthetic proteins, and other biomolecules. It also includes the development of scanning probe techniques that measure electronic properties in nanomaterials and nanodevices.

Previously, he served as the director of the Nano/Bio Interface Center at the University of Pennsylvania (2014-2017). Provided by Wikipedia
