The recent research in the Johnson group has been on multiscale computations, theoretical chemistry and surface-enhanced spectroscopies such as Raman scattering (SERS), fluorescence (SEF) and Raman optical activity (SEROA). A stint at the NSF covered the broader areas of nanochemistry and chemical theory. Johnson's current interests include improving wavelet basis techniques for describing local fields surrounding plasmonic nanoparticles, dimerization reactions for ligands attached to these nanoparticles, and formation of conducting chains of single-walled carbon nanotubes due to RF electric field radiated from a Tesla coil (Teslaphoresis). The forces in chain formation are not completely understood, and electromagnetic simulations are being implemented to investigate them.
