[1] She developed the exchange-hole dipole moment dispersion model (XDM), which describes intermolecular interactions.
[10] She was a Natural Sciences and Engineering Research Council postdoctoral fellow at Duke University with Yang Weitao from 2007 to 2010.
[15] This index describes the non-covalent interactions in a range of chemical applications, and is fast to compute, making it able to handle large systems.
[17] Johnson joined the faculty of the School of Natural Sciences at the University of California, Merced as an assistant professor in 2010.
In her independent career, Johnson has continued to develop and apply methods for London dispersion interactions using density functional theory.
Her group successfully predicted the most stable polymorph of a variety of molecular crystals using dispersion-corrected density functional theory.
