The 2018 winner of the Tom Ziegler Award is:
Erin R. Johnson is originally from Ottawa,and obtained her BSc at Carleton University in 2004. She completed her Ph.D. in chemistry at Queen's University in 2007, under the supervision of Axel Becke. She was then an NSERC post-doctoral fellow at Duke University in the group of Weitao Yang. In 2010, she became an assistant professor in the chemistry and chemical biology group at the University of California, Merced. Since July 2015, she has been an associate professor at Dalhousie University, in Halifax, where she holds the Herzberg-Becke Chair in Theoretical Chemistry. Her research focuses on development and application of density-functional theory (DFT), with an emphasis on intermolecular interactions. Notable methods co-developed by Johnson include the exchange-hole dipole moment (XDM) dispersion model the non-covalent interactions (NCI) index, and the Becke-Johnson exchange potential.
