Metrology, National Research Council Canada
Linda Johnston is currently a researcher emerita with the National Research Council (NRC). She did BSc and PhD work at Acadia University and the University of Western Ontario, respectively, and then joined the NRC to work with Keith Ingold and Tito Scaiano. Her entire career has been spent in various groups and research institutes at the NRC, since 2012 at the Metrology Research Centre. Her research interests include the development and applications of multi-modal imaging and spectroscopy tools to study nanoscale materials and biological assemblies. Recent projects focus on the characterization of cellulose nanocrystals (CNC), the development of CNC reference materials and standards, and quantification of nanomaterial surface functional groups. She led the development of a CNC reference material released by NRC in 2016 and has been active in developing national and international standards, including leading 2 published standards on CNC characterization and co-leading two current technical specifications on cellulose nanomaterial (CNM) crystallinity and methods to quantify nanomaterials surface functional groups. The standards work has involved leading 3 international interlaboratory comparisons on CNM characterization. Other activities include titular membership and secretary of IUPAC Division VII, Chemistry and Human Health, participation in a number of OECD committees and interlaboratory comparisons, and adjunct appointment in the Department of Chemistry and Biomolecular Sciences at the University of Ottawa. Johnston has co-authored over 180 publications.
